Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The radio frequency control circuit provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Radio frequency technology has a wide, irreplaceable role in the field of wireless communications. Which is a wireless communication mode that utilizes radio frequency to transmit information. Radio frequency devices are used in electronic devices for radio frequency communication, which include a Power Amplifier (PA), which is also referred to as a radio frequency Amplifier.

Referring to fig. 1, in the conventional rf PA power supply scheme for electronic devices, especially mobile terminals, power supply pins of rf PAs corresponding to different frequency bands are connected to a same node, and the same node is further connected to an output pin of a power supply. However, when a power supply line in which a certain rf PA is located is short-circuited, for example, a power supply pin of the rf PA is short-circuited to ground in most cases, or a circuit device connected in parallel outside the power supply, for example, a capacitor, is short-circuited, on one hand, a large amount of leakage current is generated in the power supply line of the rf PA, power consumption of the electronic device is accelerated, and the temperature of the device is increased. On the other hand, the other rf PAs have too low a voltage, usually lower than 0.3V, due to the short circuit of the power supply to ground, and thus the other rf PAs cannot work normally. In summary, the electronic device is completely unable to work normally, and the motherboard needs to be replaced or maintained.

In order to solve the above problems, the present application provides a radio frequency control circuit. Referring to fig. 2, fig. 2 is a block diagram of an alternative structure of the rf control circuit. In the circuit, a power supply 10, a detection module 20, a processing module 30, a switch module 40, and N rf amplifiers (not labeled) are included. Wherein N is not less than 2 and is an integer.

The power supply 10 may be configured to output a power supply voltage to a target rf amplifier (not labeled) corresponding to a resident frequency band of the N rf amplifiers.

The detection module 20 may be configured to detect an electrical parameter corresponding to a power supply line from the power supply 10 to the target rf amplifier; the detection module 20 can be connected with the power supply 10, and the detection module 20 can also be connected with the target radio frequency amplifier through the switch module 40;

the processing module 30 may be connected to the detection end of the detection module 20, and may be configured to obtain the electrical parameter from the detection module 20, shield the resident frequency band corresponding to the target rf amplifier when the electrical parameter indicates that the power consumption of the target rf amplifier is abnormal, and control the switch module 40 to cut off the power supply line.

The power supply 10 may be a power supply IC Chip (Integrated Circuit Chip). The power supply 10 may be configured to provide a supply voltage to a radio frequency power amplifier (i.e., a target radio frequency amplifier) corresponding to the parking band. The resident frequency band may refer to a frequency band where electronic devices need to reside for radio frequency communication. It should also be noted that at least one resident frequency band may exist in the electronic device at the same time.

For example, the electronic device may only have one resident frequency band at the same time, and the radio frequency amplifier corresponding to the resident frequency band is the target radio frequency amplifier.

For example, the electronic device may have M resident bands at the same time, 1 < M < N. For example, when M is 2, the detecting module 20 may detect electrical parameters corresponding to power lines from the power source 10 to the two target rf amplifiers, or may detect electrical parameters from the power source 10 to the switching module 40 (i.e., a total power line).

It is understood that, in the case that there are M resident frequency bands and the detection modules 20 respectively detect the electrical parameters of the power supply line from the power supply 10 to each target rf amplifier, the number of the detection modules 20 may be consistent with the number of the target rf amplifiers, and the detection modules 20 may be disposed between the switch module 40 and the target rf amplifiers.

When M resident frequency bands exist and the detection module 20 detects the electrical parameters of the main power supply line, when the power consumption of any target radio frequency amplifier is abnormal, the electrical parameters of the main power supply line are also changed, so that the abnormal power consumption phenomenon can be determined.

The output pin of the power supply 10 may be connected to the detection module 20, the detection module 20 may also be connected to the control terminal of the switch module 40, and the detection terminal of the detection module 20 may be connected to the processing module 30.

The detection module 20 can be configured to perform corresponding operations according to different electrical parameters, which will be described in detail later. In the embodiment of the present application, the detecting module 20 may be configured to detect and obtain an electrical parameter corresponding to a power supply line from the power supply 10 to the target rf amplifier, and then feed the electrical parameter back to the processing module 30 through the detecting terminal.

For example, the electrical parameter may be a current value corresponding to a power supply line between the power supply 10 and the target rf amplifier, a voltage value corresponding to a power supply line between the power supply 10 and the target rf amplifier, or other electrical parameters related to the electronic circuit.

The switch module 40 may be a change-over switch, which may be a single-pole multi-throw change-over switch, or may be a combination of a plurality of single-pole double-throw switches. Taking the example that the electronic device has one resident frequency band, the switch module 40 only needs to include at least one control terminal and a plurality of controlled terminals.

The control terminal of the switch module 40 is connected to the detection module 20, the controlled terminal of each switch module 40 may be correspondingly connected to one radio frequency amplifier, and the electronic device includes N radio frequency amplifiers, where the target radio frequency amplifier is at least one of the N radio frequency amplifiers. When the electronic device needs to perform radio frequency communication in a certain frequency band or certain frequency bands, the controlled end of the switch module 40 is correspondingly switched to a path of the radio frequency power amplifier corresponding to the certain frequency band/certain frequency bands to supply power to the radio frequency power amplifier.

Illustratively, N is equal to 4, i.e. the electronic device comprises 4 radio frequency amplifiers, each of which may correspond to a frequency band, i.e. there are 4 different frequency bands in the frequency band bank of the electronic device.

It is understood that the electrical parameter may be a parameter related to the power supply line, which can reflect the operation condition of the power supply line. When the power supply line operates normally, the electrical parameter may indicate that the target rf amplifier is powered normally, and at this time, the processing module 30 may continue to obtain a new electrical parameter from the detecting module 20.

On the contrary, the electrical parameter may represent that the target rf amplifier is abnormal in power consumption, and the processing module 30 may shield the frequency band corresponding to the target rf amplifier through software, and no longer use the frequency band; the target rf amplifier is shielded by hardware, that is, the switching module 40 cuts off the power supply line between the power supply 10 and the target rf amplifier, and the switching module 40 does not switch the power supply 10 to the power supply path of the corresponding PA.

In the embodiment of the application, by arranging the detection module 20 and the processing module 30 in the radio frequency control circuit, the processing module 30 obtains the electrical parameter corresponding to the power supply line between the power supply 10 and the target radio frequency amplifier, which is detected by the detection module 20; when the electrical parameters represent that the power consumption of the target radio frequency amplifier is abnormal, shielding the frequency band corresponding to the target radio frequency amplifier, and controlling the switch module 40 to cut off the power supply line. By the arrangement, the circuit with the power utilization problem is processed, the radio frequency function of the electronic equipment is reserved as far as possible, and the problem that the radio frequency system of the whole electronic equipment cannot work due to abnormal power utilization is solved. Therefore, the problem that electronic equipment cannot be used due to the fact that a certain radio frequency power amplifier is short-circuited or a circuit device connected in parallel outside the power supply 10 is short-circuited in the prior art can be solved.

Referring to fig. 2 and 3 together, in order to detect the power consumption of the target rf amplifier, in some embodiments, the current value may be set as an electrical parameter. In the case where the electrical parameter is a current value, the detection module 20 may include a resistor R, a first end of which may be connected to the power source 10, and a second end of which may be connected to the switch module 40. That is, the first terminal of the resistor R is the first terminal of the detection module 20, and the second terminal of the resistor R is the second terminal of the detection module 20.

The processing module 30 may include a first receiving end and a second receiving end; the first receiving terminal may be connected to a first terminal of the resistor R, and the second receiving terminal may be connected to a second terminal of the resistor R.

The resistor R may be a high-precision resistor, and the resistance of the resistor R may be known by the processing module 30 before the electronic device leaves the factory. The processing module 30 may be an SOC (System on Chip), and the first receiving terminal and the second receiving terminal of the processing module 30 may be two voltage detection pins of the SOC. It is understood that a SOC typically has multiple sets of voltage sense pins, and the voltage sense pins can be used for voltage sensing.

The two voltage detection pins can respectively detect the voltages at two ends of the high-precision resistor R, and the calculation is performed according to the formula I ═ V1-V2)/R, where I is the output current, V1-V2 are the voltage difference between two ends of the resistor R, and R is the resistance value of the resistor, so that the output current of the power supply 10 can be obtained, and the output current is the electrical parameter.

It is understood that when one or more rf amplifiers fail to cause short circuit of the power supply 10 or short circuit of other devices on the power supply 10, the power consumption abnormality of the target rf amplifier can be determined quickly by judging the current output condition.

In these examples, through the structural arrangement of the detection module 20, the electrical parameters are obtained by combining voltage detection and current value calculation, so that the power utilization abnormality is conveniently and quickly located, and even if a power supply of one or more radio frequency PAs is short-circuited or a peripheral parallel device of the power supply 10 is short-circuited and fails, the functions of other radio frequency PAs can be retained, so that a part of communication functions of the electronic device are ensured, the electronic device cannot be used completely, and the influence on the use of a user is reduced.

Referring to fig. 2 and 4 together, in order to detect the power consumption of the target rf amplifier, in some embodiments, the voltage value may be set as an electrical parameter. In the case where the electrical parameter is a voltage value, the detection module 20 may include a first node (not labeled), where the first node is a receiving end of the processing module 30 and a node where the power supply 10 is connected to the switch module 40.

The receiving end of the processing module 30 may be an SOC voltage detection pin, and the setting of the first node connects the output end of the power supply 10 with the SOC voltage detection pin, so that the processing module 30 can quickly detect the voltage condition to obtain a voltage value, i.e., an electrical parameter. And then, by judging the detected voltage value and comparing the detected voltage value with the voltage required to be output by the power supply 10, whether the power supply line fails or not is quickly positioned.

In these examples, the structural arrangement of the detection module 20, in combination with voltage detection and comparison, facilitates and quickly locates the power utilization anomaly.

A radio frequency control method is proposed based on the radio frequency control circuits shown in fig. 2 to 4, and referring to fig. 5, the method may include:

s501, acquiring electrical parameters corresponding to a power supply line between a power supply and a target radio frequency amplifier under the condition that the power supply supplies power to the target radio frequency amplifier;

s502, shielding the frequency band corresponding to the target radio frequency amplifier under the condition that the electrical parameters represent that the power consumption of the target radio frequency amplifier is abnormal, and controlling the power supply to stop supplying power to the target radio frequency amplifier.

The power supply may supply power to the target rf amplifier by outputting a power supply voltage to the target rf amplifier at the power supply such that the target rf amplifier is electrically operated. In the power supply process, the detection module arranged between the power supply and the switch module can detect to obtain the electrical parameters, and then the processing module obtains the electrical parameters detected by the detection module through the detection pin connected with the detection module. The processing module may acquire the electrical parameters from the detection module in real time or at a timed interval, such as every 10 milliseconds.

In case the processing module determines that the electrical parameter characterizes an electrical anomaly of the target rf amplifier, the electronic device may shield the rf PA (i.e. the target rf amplifier) from the software level, for example, remove it from the preset frequency band library of the supported frequency bands, and do not use it any more, and in addition, the processing module may control the switch module to no longer switch the power supply to the power supply path of the target rf amplifier.

In order to continue to implement normal radio frequency communication of the electronic device, after S502, the resident frequency band may be obtained again, and the power supply is controlled to supply power to a new target radio frequency amplifier, where the new target radio frequency amplifier is a radio frequency amplifier other than the target radio frequency amplifier among the N radio frequency amplifiers, and the new target radio frequency amplifier corresponds to the resident frequency band obtained by reselection.

The process of re-selecting the resident frequency band and the rf amplifier corresponding to the resident frequency band is to re-enable the rf system to resume rf communication.

In an alternative example, the process of acquiring the resident frequency band may include acquiring a usable frequency band of the electronic device; and merging the usable frequency band and the supported frequency band of the electronic equipment to obtain a target frequency band, wherein the target frequency band is the resident frequency band.

It can be understood that, due to abnormal power utilization, the frequency band corresponding to the original target rf amplifier is shielded, and therefore, when the resident frequency band is reselected and acquired, the shielded frequency band needs to be removed from the supported frequency band. Namely, the process of reselecting the camping frequency band may include: acquiring a usable frequency band of the electronic equipment; and merging the available frequency band and the supporting frequency bands of the electronic equipment except the frequency band corresponding to the target radio frequency amplifier to obtain a target frequency band, wherein the target frequency band is the resident frequency band.

Illustratively, the supported frequency bands included in the preset frequency band library of the electronic device are B1, B3, B5, B8, B40, B41, GSM850, and GSM 900. The power supply line of the target RF amplifier in the electronic device is short-circuited, and the frequency band corresponding to the short-circuited power supply line is B41, and the short-circuited power supply line is removed from the preset frequency band library. The frequency bands currently available for electronic devices are GSM850, GSM900, B41. After the union, the obtained result, that is, the target frequency band may include GSM850 and GSM900, where GSM850 and GSM900 are the camping frequency bands.

In another alternative example, the frequency band with the highest priority may be selected as the camping frequency band based on the target frequency bands including GSM850 and GSM 900. The priority may be determined by the operator of the electronic device phone card, signal strength, signal quality, etc. It should be noted that this may be the case for the initial selection of the resident band, and may also be the lack of a process for removing the band from the preset band library.

In these examples, the situation that the whole radio frequency system cannot work is avoided by obtaining the reselection of the resident frequency band and switching the power supply control of the new target radio frequency amplifier, so that the radio frequency PA with abnormal power consumption works, but other normal radio frequency PAs can be used, the realization of the radio frequency function is kept as far as possible.

To achieve unambiguous diagnosis of an electrical usage anomaly from an electrical parameter, in some examples, after S501, the method may further comprise: and determining that the target radio frequency amplifier is abnormal in electricity utilization under the condition that the electrical parameters do not accord with the parameter conditions corresponding to the target radio frequency amplifier.

In an alternative example, the electrical parameter may include a current value. In the case that the electrical parameter includes a current value, the case that the electrical parameter does not meet the parameter condition corresponding to the target radio frequency amplifier may include: the current value is larger than a first parameter threshold corresponding to the target radio frequency amplifier.

Specifically, the first parameter threshold may be set according to different target rf amplifiers, and the first parameter threshold may be the same or different. The actual first parameter threshold may be set according to a maximum working current under normal conditions before the power supply supplies power to the target rf amplifier, for example, before the electronic device leaves a factory.

In an optional example, before the power supply supplies power to the target radio frequency amplifier, the maximum operating currents corresponding to N radio frequency amplifiers may be obtained; obtaining a corresponding width limit value of each maximum working current; and respectively calculating the maximum working current corresponding to each radio frequency amplifier and the width limit value corresponding to each maximum working current to obtain the first parameter threshold value corresponding to each radio frequency amplifier.

Illustratively, the maximum operating currents of 4 rf amplifiers tested in advance are Im1, Im2, Im3 and Im4, respectively. The wide limit value is the current margin, and can be set autonomously by referring to the difference of different machines, radio frequency devices, temperature and the like, so as to prevent misjudgment. Taking the margin values Id as an example, the first parameter thresholds corresponding to the 4 rf amplifiers are Im1+ Id, Im2+ Id, Im3+ Id and Im4+ Id, respectively. Of course, in other examples, the grace value may also be represented according to a grace ratio, which is not described herein in detail.

In the above example, the setting process of the first parameter threshold is shown, and it is possible to provide accurate parameters for detecting the power consumption abnormality while preventing erroneous determination in consideration of errors.

The power consumption abnormality diagnosis may be that when the current value acquired by the processing module is smaller than a first parameter threshold value, the power consumption of the target radio frequency amplifier is considered to be normal, the power supply is not abnormal, and no action is performed or the detection module returns to continue acquiring new power parameters.

When the current value acquired by the processing module is greater than or equal to the first parameter threshold, it is considered that the power consumption of the target radio frequency amplifier is abnormal, and software and hardware shielding processing needs to be continuously executed, for example, the frequency band of the target radio frequency amplifier is removed from the preset frequency band library.

In the examples, the power utilization abnormity diagnosis of the radio frequency amplifier is realized through the current value, and the rapid abnormity positioning is facilitated.

To enable power up anomaly localization of a radio frequency amplifier, in some embodiments, the electrical parameter may include a voltage value; in the case where the electrical parameter includes a voltage value, the case where the electrical parameter does not meet a parameter condition corresponding to the target radio frequency amplifier may include:

the voltage value is smaller than a first preset voltage threshold value, and/or the difference between a power supply voltage value corresponding to the real-time output power of the electronic equipment and the voltage value is larger than a second preset voltage threshold value.

It should be noted that, in the mainstream scheme of the current radio frequency power supply control, the power supply voltage output by the power supply is continuously adjusted along with the output power, that is, a higher power supply voltage is used for high power, and a lower power supply voltage is used for low power to reduce power consumption.

When the corresponding electronic equipment is used, a parameter table is arranged in the corresponding electronic equipment, the actual output power (P & ltI & gt U & gt) of the circuit can be obtained, then the actual power supply voltage is adjusted according to the parameter table searching reference, and the parameter table can be a relation table corresponding to the output power and the power supply voltage value. The method can further be a corresponding relation table of the output power of the power supply and the voltage value of the power supply under different frequency bands.

As an example, table 1 below is a table of the relationship between the output power and the power supply voltage of the electronic device.

Power (dBm)	25	24	23	22	21	……	-45
								Voltage (v)	4	3.9	3.8	3.7	3.5	……	0.6

TABLE 1

When the radio frequency control scheme is operated, the voltage value between actual power supply lines (namely, the actual voltage value Vout serving as an electrical parameter) can be detected, and then the voltage value is compared with an ideal voltage value corresponding to the target radio frequency amplifier. It can be understood that, based on the above table 1, the ideal voltage value is the corresponding power voltage value Vc at different powers.

In an alternative example, when the difference between the ideal voltage value Vc and the actually output voltage value Vout is greater than the preset voltage threshold Vm1 (i.e., the second preset voltage threshold), it may be considered that the difference between the actual voltage value and the required voltage of the target rf amplifier is too large, and the target rf amplifier is abnormal in power consumption, and needs to be further subjected to software and hardware shielding processing.

When the difference between the ideal voltage value Vc and the actually output voltage value Vout is smaller than the preset voltage threshold Vm1, the target rf amplifier may be considered to be powered normally, and no processing may be performed, or a new electrical parameter may be obtained from the detection module.

When the difference between the ideal voltage value Vc and the actually output voltage value Vout is equal to the preset voltage threshold value Vm1, the setting may be performed according to actual needs, for example, no processing may be performed, or a return may be made to obtain new electrical parameters again, or a masking process may be performed.

In another alternative example, to further prevent the misjudgment, the comparison with the preset voltage threshold Vm2 (i.e. the first preset voltage threshold) may be added on the basis of comparing the ideal voltage value Vc with the actually output voltage value Vout. For example, as can be seen from table 1 above, in a normal situation, the power voltage value of the actual power output, even the minimum power voltage value, is usually greater than or equal to 0.6V, the preset voltage threshold Vm2 may be set to 0.5V, and the preset voltage threshold Vm2 may be other reasonable values. For example, the preset voltage threshold Vm2 may be set to a number less than the minimum power supply voltage value, such as 0.55V. When the measured voltage value Vout between the power supply lines is less than Vm2, the actual voltage value is considered to be too low, the power consumption of the target radio frequency amplifier is abnormal, and the power supply circuit is abnormal and needs to be shielded.

In a specific example, when the target rf amplifier operates, when the voltage value is obtained by the detection module, whether the voltage value is smaller than a first preset voltage threshold may be first compared, and when the voltage value is smaller than the first preset voltage threshold, it is considered that the actual voltage value is too low, and the power supply circuit where the target rf amplifier is located is abnormal, so that the target rf amplifier may be shielded.

When the voltage value is greater than or equal to the first preset voltage threshold, the actual output power of the current electronic equipment can be obtained, then the power supply voltage value which should be reached by the electronic equipment during the actual output power is obtained according to the actual output power, and then whether the difference between the power supply voltage value and the measured voltage value is greater than the second preset voltage threshold or not is judged.

When the difference between the power supply voltage value and the voltage value is larger than a second preset voltage threshold value, the difference between the actual voltage value and the power supply voltage required by the target radio frequency amplifier is considered to be overlarge, the power consumption of the target radio frequency amplifier is abnormal, and software and hardware shielding treatment is required to be further carried out.

When the difference between the voltage value of the power supply and the voltage value is smaller than or equal to a second preset voltage threshold value, the fact that the current target radio frequency amplifier is normal in power consumption is represented, processing is not needed temporarily, and the voltage value can be continuously monitored.

By preferentially using the first preset voltage threshold value for comparison, it is possible to perform early screening for a case where the voltage value is significantly abnormal. Of course, in other examples, the determination according to the first preset voltage threshold and the second preset voltage threshold may be performed simultaneously, or the comparison of the voltage values according to the real-time output power and the second preset voltage threshold may be performed first, and then the comparison may be performed according to the first preset voltage threshold.

In addition, in a case that the voltage value is small, for example, the voltage value is 0.4V, a deviation between the voltage value and a power supply voltage value corresponding to the actual output power may also be large, that is, the voltage value is not less than the first preset voltage threshold, and a difference between the voltage value and the power supply voltage value is not less than the second preset voltage threshold, which also belongs to the protection range of the present application, and also represents that the power consumption of the target rf amplifier is abnormal, and a shielding process is required.

In these examples, a preset voltage threshold Vm1, or a preset voltage threshold Vm1 and Vm2, is added to compare the actually output voltage value Vout, so as to facilitate and quickly implement the power consumption abnormality diagnosis of the target radio frequency amplifier.

Another embodiment of the present application further provides a radio frequency control device, which may include an obtaining module, a shielding module, and a control module.

The acquisition module can be used for acquiring electrical parameters corresponding to a power supply line between a power supply and a target radio frequency amplifier under the condition that the power supply supplies power to the target radio frequency amplifier;

the shielding module may be configured to shield a frequency band corresponding to the target radio frequency amplifier when the electrical parameter represents that the target radio frequency amplifier is abnormal in power consumption.

A control module operable to control the power supply to stop supplying power to the target radio frequency amplifier.

In an optional example, the obtaining module may be further configured to re-obtain the camping frequency band;

the control module may be further configured to control the power supply to supply power to a new target radio frequency amplifier, where the new target radio frequency amplifier is a radio frequency amplifier other than the target radio frequency amplifier among the N radio frequency amplifiers, and the new target radio frequency amplifier corresponds to the reselected reserved frequency band.

In another optional example, the obtaining module may include:

the acquisition unit can be used for acquiring the usable frequency band of the electronic equipment;

and the processing unit may be configured to obtain a target frequency band by merging the available frequency band and the supported frequency band of the electronic device, where the target frequency band is the reserved frequency band.
