Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a flowchart illustrating a method for determining a radio frequency communication configuration parameter according to an embodiment of the present invention. The method is applicable to the case of determining the configuration parameters of the radio frequency power amplifier, and can be executed by a radio frequency communication configuration parameter determination device, which can be composed of hardware and/or software and can be generally integrated in a computer device. The method specifically comprises the following steps:
s110, obtaining a gain coefficient as a target gain coefficient within a gain coefficient range of a power amplifier set in the radio frequency equipment.
In this embodiment, the radio frequency device may be a device having a wireless radio frequency communication function, such as a smart phone, and the radio frequency device includes a radio frequency circuit for performing radio frequency communication, and the radio frequency circuit includes a power amplifier PA for amplifying a radio frequency signal to perform wireless transmission in a desired channel.
Taking a mobile phone as an example, specifically, the device connection mode shown in fig. 1b may be used to optimize the radio frequency communication configuration parameters. The mobile phone 1 to be tested is powered by the program-controlled current source 2, and the program-controlled current source 2 can display voltage and current values; the computer equipment 3 controls the mobile phone 1 to be tested through the USB, so that the mobile phone 1 to be tested works under different PA gain coefficients, currents and voltages; the comprehensive tester 4 is connected with a radio frequency test seat on the mobile phone 1 to be tested through a radio frequency Cable (radio frequency connecting wire), and analyzes a radio frequency signal of the mobile phone 1 to be tested; the computer device 3 is connected with the comprehensive tester 4 through a GPIB (General-Purpose-Interface Bus) to monitor the ACLR index of the radio frequency signal; the computer device 3 is connected with the program control current source 2 through the GPIB to monitor the working current of the mobile phone 1 to be tested.
For example, in this embodiment, before optimizing the radio frequency communication configuration parameters of the PA in the radio frequency device, a gain coefficient range may be preset, so that the PA gain coefficient RGI may be adjustable within the gain coefficient range. Specifically, an RGI range may be preset in the computer device, each RGI may be optimized once in the RGI range, and the optimal transistor quiescent current ICQ and the optimal transistor supply voltage VCC corresponding to each RGI condition are respectively determined, so that the radio frequency device may invoke the corresponding optimized parameter to transmit the radio frequency signal no matter which RGI is adopted, thereby reducing the power consumption of the device while ensuring the quality of the radio frequency signal. Each RGI can respectively correspond to one PA transmitting power, under a certain PA transmitting power, the optimal ACLR can be obtained by adjusting the ICQ, and the radio frequency index ACLR and the PA working current can be adjusted by adjusting the VCC, so that the set RGI range preferably covers the dynamic range of the whole PA transmitting power.
As a practical example, the traversal may be made starting from the maximum value within the RGI range, e.g. setting the maximum value to 72, then RGI =72 may be taken as the target gain factor first. Of course, the parameter optimization may also be performed by starting from the minimum value in the RGI range or according to other traversal manners, which is not limited herein.
Optionally, before obtaining a gain coefficient as a target gain coefficient within a range of gain coefficients of a power amplifier set in the radio frequency device, the method further includes: receiving a debugging instruction aiming at a radio frequency circuit of radio frequency equipment, wherein the debugging instruction is used for indicating the radio frequency circuit to carry out impedance matching; and performing matching debugging on the radio frequency circuit according to the debugging instruction so as to reduce the insertion loss of the radio frequency circuit to the minimum.
For example, before parameter optimization, matching and debugging may be performed on the radio frequency device, specifically, an inductance capacitance value of a radio frequency circuit in the radio frequency device is adjusted, so that insertion loss of the radio frequency circuit is reduced to the minimum. The impedance matching has the advantage that interference errors in the process of optimizing radio frequency communication configuration parameters can be reduced.
And S120, determining the optimal transistor quiescent current corresponding to the target gain coefficient according to the target gain coefficient and the preset transistor power supply voltage.
In this embodiment, the preset transistor power supply voltage may be a preset maximum transistor power supply voltage, wherein different target gain coefficients may correspond to the same preset transistor power supply voltage. For example, the transistor quiescent current may be adjusted under the conditions of the target gain factor and the preset transistor supply voltage, so as to find the value of the transistor quiescent current under the conditions with the best signal quality, and the transistor quiescent current under the condition with the best signal quality may be used as the optimal transistor quiescent current.
Optionally, determining an optimal transistor quiescent current corresponding to the target gain coefficient according to the target gain coefficient and a preset transistor power supply voltage, includes: under the target gain coefficient and the preset transistor power supply voltage, sequentially selecting transistor quiescent currents within a set transistor quiescent current range to emit radio frequency signals, and acquiring adjacent channel carrier leakage ratio ACLR indexes of the radio frequency signals corresponding to the transistor quiescent currents; and determining the transistor static current corresponding to the largest ACLR index in the ACLR indexes as the optimal transistor static current corresponding to the target gain coefficient.
In this embodiment, a transistor quiescent current range may be preset, and the transistor quiescent current range may include a plurality of ICQ reference values, where the ICQ reference value may be set based on the ICQ recommended value provided by the supplier, specifically, an optimal ICQ recommended value may correspond to each PA power level supplier, and may be appropriately adjusted according to the ICQ recommended value to cover all values recommended by the supplier, and of course, the present invention is not limited to these values.
Illustratively, under a set RGI and a maximum VCC (e.g., set to 3.3 v), an ICQ scan is performed and the ICQ value with the best ACLR index margin is found. Specifically, by issuing a power-up command to the mobile phone, where the radio frequency communication configuration parameter is (RGI, ICQ, VCC), and the PA gain RGI is a current target gain coefficient, for example, at this time, target RGI =72, and PA supply voltage VCC is 3.3v, all ICQ values in the transistor quiescent current range are sequentially used, and by reading and recording a corresponding ACLR value under each ICQ value, an ICQ value corresponding to a maximum ACLR value is obtained, and the ICQ value is an optimal ICQ value under the current target RGI.
And S130, acquiring the optimal transistor power supply voltage corresponding to the target gain coefficient according to the target gain coefficient and the optimal transistor quiescent current.
In the linear PA characteristic, for a specific power class of a specific frequency band, that is, under the condition of a target gain coefficient, there is always an optimal ICQ value so that the ACLR index of the PA reaches the optimal state, therefore, by determining the optimal ICQ respectively corresponding to different RGIs, the ACLR index can have sufficient margin, that is, excessive performance, in this case, the ACLR index margin can be reduced by changing the value of VCC until the ACLR index just reaches the standard, thereby determining VCC in this state as the optimal transistor supply voltage.
S140, determining the target gain coefficient, the optimal transistor quiescent current and the optimal transistor power supply voltage as radio frequency communication configuration parameters of the radio frequency equipment under the target gain coefficient, returning to execute in a gain coefficient range of a power amplifier set in the radio frequency equipment, and acquiring a gain coefficient as the target gain coefficient until all gain coefficients contained in the set gain coefficient range of the power amplifier are traversed.
For example, after determining the optimal transistor quiescent current and the optimal transistor supply voltage under the condition of the target gain coefficient, the optimal transistor quiescent current and the optimal transistor supply voltage are the optimal configuration values under the power class, that is, the optimal radio frequency communication configuration parameters under the target gain coefficient can be represented as (RGI, ICQ, VCC), where RGI is the target gain coefficient, ICQ is the optimal transistor quiescent current, and VCC is the optimal transistor supply voltage. And finally, detecting whether the RGIs in the set PA gain coefficient range are all scanned completely, if not, issuing an RGI scanning instruction, repeating the steps until all the RGIs are scanned completely, and further obtaining radio frequency communication configuration parameters corresponding to all the RGIs with the least power consumption.
For example, in this embodiment, all gain coefficients within a range of gain coefficients of a power amplifier are sequentially scanned and are respectively used as target gain coefficients to perform parameter optimization, so as to obtain radio frequency communication configuration parameters respectively corresponding to each gain coefficient, thereby obtaining optimal radio frequency communication configuration parameters of a PA.
According to the technical scheme of the embodiment, a gain coefficient is obtained as a target gain coefficient within a gain coefficient range of a power amplifier set in radio frequency equipment, an optimal transistor quiescent current corresponding to the target gain coefficient is determined according to the target gain coefficient and a preset transistor power supply voltage, an optimal transistor power supply voltage corresponding to the target gain coefficient is obtained according to the target gain coefficient and the optimal transistor quiescent current, the target gain coefficient, the optimal transistor quiescent current and the optimal transistor power supply voltage are determined as radio frequency communication configuration parameters of the radio frequency equipment under the target gain coefficient, and the radio frequency communication configuration parameters are returned to perform the steps in a circulating mode until all gain coefficients included in the set gain coefficient range of the power amplifier are traversed.
Example two
Fig. 2 is a flowchart illustrating a method for determining a radio frequency communication configuration parameter according to a second embodiment of the present invention. The present embodiment is optimized based on the above embodiments, and provides a method for determining an optimal radio frequency communication configuration parameter, specifically, further optimizing the obtaining of an optimal transistor supply voltage corresponding to a target gain coefficient according to the target gain coefficient and an optimal transistor quiescent current. The method specifically comprises the following steps:
s210, obtaining a gain coefficient as a target gain coefficient within a gain coefficient range of a power amplifier set in the radio frequency equipment.
And S220, determining the optimal transistor quiescent current corresponding to the target gain coefficient according to the target gain coefficient and the preset transistor power supply voltage.
And S230, under the target gain coefficient and the optimal transistor static current, sequentially selecting the transistor power supply voltage in the set transistor power supply voltage range to emit radio frequency signals, and acquiring ACLR indexes of the radio frequency signals corresponding to the transistor power supply voltages.
In this embodiment, the set transistor supply voltage range may be a preset VCC scan range, and when the optimal VCC corresponding to the target RGI is obtained, the scan may be performed within the transistor supply voltage range.
Specifically, after the optimal ICQ is obtained, VCC scanning is performed, and a power enforcement instruction (RGI, ICQ, VCC) is issued to the radio frequency device by the computer device, instructing the radio frequency device to transmit a radio frequency signal according to the parameter, where RGI is a target RGI, ICQ is the optimal ICQ, and VCC is the currently scanned VCC. And then, sequentially selecting each power supply voltage VCC within a set transistor power supply voltage range according to a preset mode, and connecting a computer device with a comprehensive tester to monitor and record the current ACLR value. The preset selection manner includes, but is not limited to, a manner from a large VCC value to a small VCC value, or a manner from a small VCC value to a large VCC value.
Optionally, the transistor supply voltage range includes a first supply voltage range and a second supply voltage range, where values of the transistor supply voltage included in the first supply voltage range are both greater than values of the transistor supply voltage included in the second supply voltage range.
Correspondingly, in the scope of the set transistor supply voltage, the transistor supply voltage is selected in turn to transmit the radio frequency signal, including: if the value of the target gain coefficient is larger than a preset coefficient threshold value, sequentially selecting the transistor power supply voltage from large to small within a first power supply voltage range to transmit a radio frequency signal; and if not, sequentially selecting the transistor power supply voltage from large to small within the second power supply voltage range to transmit the radio-frequency signal.
Illustratively, the VCC range may be set in two stages according to high gain and low gain, for example, the high gain sweep range is set to 3.8v to 1.2v, and the low gain sweep range is set to 1.2v to 0.6v. The first supply voltage range may correspond to a high gain scan range, and the second supply voltage range may correspond to a low gain scan range.
The RGI with high gain and the RGI with low gain can respectively scan different power supply voltage ranges correspondingly, for example, the RGI with high gain only scans a first power supply voltage range, and the RGI with low gain only scans a second power supply voltage range, wherein if the value of the target RGI is larger than a preset coefficient threshold, the RGI can be determined to belong to high gain, otherwise, the RGI can be determined to belong to low gain. Specifically, after the supply voltage scan range is determined, the VCC is continuously decreased in the range, so that the ACLR is continuously deteriorated, and when the minimum limit condition is approached, the scan is stopped, and thus it is determined that the current VCC is the optimal VCC.
The beneficial effects of setting two scanning ranges and scanning the values of all VCC from large to small in sequence are that the efficiency of searching the best VCC can be improved, and the optimization efficiency of radio frequency communication configuration parameters is improved.
And S240, when a target ACLR index in the ACLR indexes meets a preset minimum limiting condition, determining a transistor power supply voltage corresponding to the target ACLR index to be an optimal transistor power supply voltage corresponding to a target gain coefficient.
In this embodiment, an ACLR margin minimum limit condition may be preset, and when the target ACLR index just reaches the preset minimum limit condition, it may be determined that the VCC corresponding to the target ACLR index is the optimal VCC corresponding to the target RGI.
Optionally, a target ACLR index in the ACLR indexes meets a preset minimum limiting condition, which includes: the value of the target ACLR indicator in the ACLR indicator is greater than a preset minimum threshold, and the value of the target ACLR indicator is closest to the preset minimum threshold in the ACLR indicator.
For example, the preset minimum threshold may be a preset threshold ACLR Limit of the adjacent channel carrier leakage ratio indicator, and only when the preset minimum threshold is greater than the preset minimum threshold, the radio frequency communication quality can be ensured. Therefore, when the ACLR indicator falls to just above the preset minimum threshold, that is, when the value of the target ACLR indicator is greater than the preset minimum threshold and is closest to the preset minimum threshold in the ACLR indicator, it is determined that the target ACLR indicator satisfies the preset minimum limiting condition.
The advantage of this arrangement is that the power consumption of the radio frequency device can be reduced while ensuring that the quality of the radio frequency communication is not affected.
And S250, determining the target gain coefficient, the optimal transistor quiescent current and the optimal transistor power supply voltage as radio frequency communication configuration parameters of the radio frequency equipment under the target gain coefficient.
S260, determining whether all gain coefficients contained in the set range of the gain coefficients of the power amplifier are traversed or not, and if not, returning to execute S210; if yes, the process is ended.
In the technical scheme of this embodiment, on the basis of the above embodiment, after determining the optimal transistor quiescent current corresponding to the target gain coefficient, the transistor power supply voltage is sequentially selected within the set transistor power supply voltage range to emit the radio frequency signal, and the ACLR index of the radio frequency signal corresponding to each transistor power supply voltage is obtained by continuing to select the transistor power supply voltage within the set transistor power supply voltage range under the target gain coefficient and the optimal transistor quiescent current.
On the basis of the foregoing embodiments, optionally, the method further includes: establishing a radio frequency parameter table according to radio frequency communication configuration parameters corresponding to each gain coefficient within a set gain coefficient range of the power amplifier; and storing the radio frequency parameter table to the radio frequency equipment so that the radio frequency equipment calls the radio frequency communication configuration parameters in the radio frequency parameter table to carry out radio frequency communication.
As an actual example, after the radio frequency communication configuration parameters respectively corresponding to each gain coefficient are optimized, the established radio frequency parameter table may be as shown in table 1:
TABLE 1 RF parameter table
Illustratively, the radio frequency parameter table obtained by the method can be written into a memory of the radio frequency equipment, and when the radio frequency equipment performs radio frequency communication, the parameter is called for communication, so that the power consumption of the equipment is reduced while the quality of the radio frequency communication is ensured. Certainly, the method can also be extended to all systems and all frequency bands supported by the radio frequency equipment to obtain an (RGI, ICQ, VCC) radio frequency parameter table covering all systems and frequency bands, when the radio frequency equipment is actually used, the (RGI, ICQ, VCC) processing unit of the CPU issues a control instruction to control the DC-DC to dynamically adjust the power supply voltage VCC of the PA, the ICQ of the PA is controlled through the MIPI, and the PA works according to the preconfigured radio frequency communication configuration parameters, so that the purposes of meeting the radio frequency performance requirement and reducing the power consumption of the radio frequency equipment are achieved.
