Description
Technical Field
The application relates to the technical field of radio frequency processing, in particular to a method and a device for detecting a radio frequency power amplifier of a mobile terminal.
Background
The call is one of the most basic functions of a mobile terminal, and a Radio Frequency Power Amplifier (RFPA) is a main part of a transmission system, and its importance is self-evident. In the front stage circuit of the transmitter, the radio frequency signal power generated by the modulation oscillation circuit is very small, and the radio frequency signal can be fed to an antenna to be radiated after sufficient radio frequency power is obtained through a series of amplification (a buffer stage, an intermediate amplification stage and a final power amplification stage). In order to obtain a sufficiently large radio frequency output power, a radio frequency power amplifier must be employed. After the modulator generates the rf signal, the rf modulated signal is amplified to sufficient power by the rf amplifier, passed through the matching network, and transmitted by the antenna. Because there are many radio frequency bands supported in the prior art, the radio frequency power amplifier configuration used in each band may be different, although the software of the mobile terminal writes the relevant configuration instruction, because there is always a precedence relationship in the instruction issue, in the prior art, it is often necessary to delay a time (e.g. 0.1 second) after all the radio frequency power amplifier start instructions are issued in configuring the band to consider that the configuration is completed, and then perform the next operation. For example, when the mobile terminal is switched from LTE BAND5 to WCDMA BAND1 at 178.000 seconds, it needs to issue a start instruction to 4 sequential rf power amplifiers, and then wait for 0.1 second delay to consider that 4 rf power amplifiers have started, and start the next operation, but in fact, this 0.1 second delay is designed with a large margin, and it is likely that 4 rf power amplifiers have started at 0.04 seconds.
Therefore, the prior art has defects and needs to be improved and developed.

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 only a part of the embodiments of the present application, and not all of the embodiments. 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 embodiment of the application provides a method and a device for detecting a radio frequency power amplifier of a mobile terminal. The mobile terminal of the embodiment of the application can be a mobile phone, a tablet computer, a notebook computer and other devices.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
A method for detecting a radio frequency power amplifier of a mobile terminal comprises the following steps: presetting a configuration state resistance value of a radio frequency power amplifier, calculating a resistance value of a radio frequency power amplifier detection module, comparing the resistance value of the radio frequency power amplifier detection module with the configuration state resistance value, wherein the resistance value of the radio frequency power amplifier detection module is not equal to the configuration state resistance value, starting the radio frequency power amplifier, the resistance value of the radio frequency power amplifier detection module is equal to the configuration state resistance value, and completing the configuration of the radio frequency power amplifier.
As shown in fig. 1, the specific flow of the method may be as follows:
101. and presetting the configuration state resistance value of the radio frequency power amplifier.
For example, when a mobile terminal connects to a frequency band, it needs to start a radio frequency power amplifier corresponding to the frequency band. And presetting the configuration state of the radio frequency power amplifier corresponding to the frequency band according to the frequency band switched by the mobile terminal, and obtaining the configuration state resistance value of the radio frequency power amplifier according to the configuration state of the radio frequency power amplifier.
The frequency band and the radio frequency power amplifier correspond to each other in two ways: one frequency band corresponds to one radio frequency power amplifier or a plurality of frequency bands correspond to one radio frequency power amplifier. Before the mobile terminal switches the frequency band, the states of the radio frequency power amplifiers of the mobile terminal include an on state or an off state, and when the mobile terminal switches the frequency band, one or more radio frequency power amplifiers need to be turned on. The configuration state of the radio frequency power amplifier is the state of the radio frequency power amplifier of the mobile terminal when the mobile terminal switches the frequency band.
The preset configuration state of the radio frequency power amplifier is the preset configuration state resistance value of the radio frequency power amplifier, because the on state and the off state of the radio frequency power amplifier correspond to different resistance values. Therefore, the configuration state resistance of the rf power amplifier includes an on state resistance and an off state resistance.
Each radio frequency power amplifier is provided with a matching resistor, the resistance value in the off state is the resistance value of the radio frequency power amplifier, and the resistance value in the on state is the resistance value of the matching resistor. Different radio frequency power amplifiers are provided with different matching resistors, the resistance values of the different matching resistors are unequal, and the requirement that a plurality of matching resistors are unequal after being connected in parallel is met. The number of the radio frequency power amplifiers is not limited, and the number of the matching resistors is the same as that of the radio frequency power amplifiers.
When the radio frequency power amplifier is detected to be closed, the matching resistor of the radio frequency power amplifier is not effective, and the resistance value of the closed state of the radio frequency power amplifier is the resistance value of the radio frequency power amplifier; when the radio frequency power amplifier is detected to be started, the matching resistor takes effect, and the resistance value of the starting state of the radio frequency power amplifier is the resistance value of the matching resistor. The matching resistor can be connected with the radio frequency power amplifier, and the control end of the radio frequency power amplifier is connected to the control end of the matching resistor; the matching resistor and the radio frequency power amplifier can also be not connected, and the matching resistor is directly arranged in the radio frequency power amplifier.
The resistance value corresponding to the state of the radio frequency power amplifier is stored in a memory of the mobile terminal, and after the resistance value of the radio frequency power amplifier is calculated, the state of the radio frequency power amplifier can be known according to the corresponding relation stored in the memory.
102. And calculating the resistance value of the radio frequency power amplifier detection module.
For example, the output end of the rf power amplifier is synchronously connected to the rf power amplifier detection module in advance, and when the mobile terminal switches the frequency band, the state of the rf power amplifier is obtained by calculating the resistance value of the rf power amplifier detection module, that is, the resistance value of the rf power amplifier at the time. Each radio frequency power amplifier is correspondingly connected with one radio frequency power amplifier detection module.
The radio frequency power amplifier is characterized in that a calculation resistor R0 is arranged, one end of a calculation resistor R0 is connected with a power supply voltage VDD, the other end of a calculation resistor R0 is connected with one end of a radio frequency power amplifier, a plurality of radio frequency power amplifiers are connected in parallel, the other end of the radio frequency power amplifier is connected with a ground end, and a central processing unit is arranged between the connection of the calculation resistor R0 and the radio frequency power amplifier.
Wherein, let Rj be the resistance value of the detection module of the rf power amplifier, Rj ═ Vgpio × R0/(VDD-Vgpio); vgpio is the voltage at the CPU pin, VDD is the power supply voltage, and R0 is the resistance of the computational resistor. The resistance value of the calculation resistor R0 is known, the setting of the resistance value of the calculation resistor R0 is not limited in the present application, and the calculation resistor R0 is only used for calculating the resistance value of the rf power amplification module.
Fig. 2 is a connection schematic diagram of a detection circuit of a radio frequency power amplifier according to an embodiment of the present disclosure. Referring to fig. 2, taking four rf power amplifiers connected in parallel as an example, one end of the calculating resistor 201 is connected to the power voltage VDD, the other end of the calculating resistor 201 is connected to one end of the rf power amplifiers 211, 212, 213, and 214 connected in parallel, the other end of the rf power amplifiers 211, 212, 213, and 214 connected in parallel is connected to the ground, and the cpu 202 is disposed between the calculating resistor 201 and the rf power amplifiers.
In the embodiment of the present application, the resistance values of the rf power amplifiers 211, 212, 213, and 214 are set to R1, R2, R3, and R4, respectively, and the resistance values of the matching resistors of the rf power amplifiers 211, 212, 213, and 214 are R11, R22, R33, and R44, respectively. Before the mobile terminal switches the frequency band, it is assumed that all the rf power amplifiers are turned off, i.e. the resistance values of the rf power amplifiers are R1, R2, R3, and R4, respectively. When the mobile terminal switches the frequency band, the radio frequency power amplifier 211 needs to be turned on, and the configuration state of the radio frequency power amplifier is preset to be that the radio frequency power amplifier 211 is turned on, and the radio frequency power amplifiers 212, 213, and 214 are kept off, that is, the resistance value of the configuration state of the radio frequency power amplifier is that the resistance value of the radio frequency power amplifier 211 is R11, and the resistance values of the radio frequency power amplifiers 212, 213, and 214 are still R2, R3, and R4. Calculating the resistance value of the rf power amplifier detection module, and if the resistance value of the rf power amplifier detection module of the rf power amplifier 211 is R11, which is the same as the configuration state resistance value, it indicates that the rf power amplifier 211 is turned on; if the resistance of the rf power amplifier detection module of the rf power amplifier 211 is R1, which is different from the configuration state resistance, it indicates that the rf power amplifier 211 is not turned on, and the mobile terminal turns on the rf power amplifier 211. And if the calculated resistance value of each radio frequency power amplifier detection module is the same as the resistance value of the configuration state, the configuration of the radio frequency power amplifier is completed.
Before the frequency band is switched, the initial state of the radio frequency power amplifier comprises an opening state and a closing state, and comprises two conditions: all closed or partially closed and partially open. When the frequency band is switched, the mobile terminal sends configuration instructions to all the radio frequency power amplifiers, if the resistance value of the radio frequency power amplifier detection module is not changed from the resistance value required by the instruction, no operation is performed, otherwise, the radio frequency power amplifiers are configured according to the resistance value of the current instruction.
103. And comparing the resistance value of the radio frequency power amplifier detection module with the configuration state resistance value.
For example, when the frequency band of the mobile terminal is switched, the resistance value of the rf power amplifier is detected. Comparing the resistance value of the detection module of the radio frequency power amplifier with the preset configuration state resistance value can know whether the radio frequency power amplifier completes configuration at the moment.
104. And the resistance value of the radio frequency power amplifier detection module is not equal to the resistance value of the configuration state, and the radio frequency power amplifier is started.
For example, the resistance value of the rf power amplifier detection module is the resistance value of the rf power amplifier at this time, and the resistance value of the rf power amplifier is different from the resistance value of the configuration state at this time, which indicates that the rf power amplifier is not turned on yet, and the mobile terminal turns on the rf power amplifier.
The opening and closing of the radio frequency power amplifier are controlled by the central processing unit.
105. And the resistance value of the radio frequency power amplifier detection module is equal to the resistance value of the configuration state, and the configuration of the radio frequency power amplifier is completed.
For example, the resistance value of the rf power amplifier detection module is the resistance value of the rf power amplifier at this time, and the resistance value of the rf power amplifier is the same as the resistance value of the configuration state at this time, which indicates that the configuration of the rf power amplifier is completed.
In order to better implement the method, an embodiment of the present application may further provide a device for detecting a radio frequency power amplifier of a mobile terminal, where the device may be specifically integrated in a network device, and the network device may be a mobile terminal or the like.
For example, as shown in fig. 3, the apparatus may include a presetting unit 301, a calculating unit 302, and a comparing unit 303, as follows:
(1) preset unit 301
The preset unit 301 is configured to preset a configuration state resistance value of the radio frequency power amplifier.
For example, the configuration state resistance of the rf power amplifier includes an on state resistance and an off state resistance. According to the frequency band switched by the mobile terminal, the configuration state of the radio frequency power amplifier corresponding to the frequency band is preset, and the resistance value of the configuration state of the radio frequency power amplifier is obtained according to the configuration state of the radio frequency power amplifier.
(2) Computing unit 302
A calculating unit 302, configured to calculate a resistance value of the rf power amplifier detection module.
For example, when the mobile terminal switches the frequency band, the resistance value of the detection module of the radio frequency power amplifier is the resistance value of the radio frequency power amplifier at that time, and the state of the radio frequency power amplifier at that time is obtained by calculating the resistance value of the detection module of the radio frequency power amplifier.
The calculating unit further comprises a calculating resistor and a central processing unit, one end of the calculating resistor is connected with the radio frequency power amplifier detection module, and the other end of the calculating resistor is connected with the power supply voltage; and a pin of the central processing unit is connected with the calculating resistor and the radio frequency power amplifier detection module.
(3) Comparison unit 303
A comparing unit 303, configured to compare the resistance value of the rf power amplifier detection module with the configuration state resistance value.
For example, the resistance of the detection module of the rf power amplifier is compared with the preset configuration state resistance, so as to know whether the configuration of the rf power amplifier is completed. The resistance value of the radio frequency power amplifier detection module is the resistance value of the radio frequency power amplifier when the frequency band of the mobile terminal is switched.
If the resistance values of the radio frequency power amplifier detection module and the configuration state are different, the radio frequency power amplifier is not started, and the mobile terminal starts the radio frequency power amplifier. And if the resistance value of the radio frequency power amplifier detection module is the same as that of the configuration state, the configuration of the radio frequency power amplifier is finished.
