Detailed Description
In order to make the technical solution of the present invention more clear and obvious to those skilled in the art, the present invention will be described in further detail with reference to examples and drawings, but the embodiments of the present invention are not limited thereto.
The radio frequency output power calibration method provided by the embodiment comprises the following steps:
step 1, an upper computer controls a signal source to output signals with different frequencies and different amplitudes and send the signals to a radio frequency power amplifier so as to simulate different working conditions possibly encountered by the radio frequency power amplifier in practical application;
step 2, the radio frequency power amplifier transmits energy to a power load (the amplified radio frequency signal (electromagnetic wave energy) is transmitted to the power load), the power load is an output load for simulating the actual working state of the radio frequency power amplifier, the output load receives and consumes the energy from the radio frequency power amplifier and is used for testing the performance of the radio frequency power amplifier, and therefore the working state of the radio frequency power amplifier is ensured to be similar to the working state in the actual application in the calibration process;
step 3, measuring the power output by the power load by using a power meter, and acquiring the actual output power by the upper computer through the power meter, wherein the step is to acquire the actual output power value of the radio frequency power amplifier under different input signals to serve as a reference of a subsequent calibration process;
step 4, reading the voltage value converted by the detector from the radio frequency power amplifier, and carrying out A/D conversion on the voltage value to obtain a corresponding A/D value;
calculating corresponding output power parameter values according to the detected A/D values through P=kv+b, wherein P is output power, v is the A/D value corresponding to the output voltage of the detector, and the parameter values are then sent to a radio frequency power amplifier control system to realize control of a power amplifier;
the step 4 specifically comprises the following steps:
step 4.1, subdividing the whole frequency band of the radio frequency power amplifier into a plurality of frequency bands (sub-frequency bands) when the power is calibrated, wherein the width of each sub-frequency band can be the same or different;
in this way, it can be ensured that the relation between the output power and the corresponding A/D value of the detector output voltage is nearly linear in each sub-band, for example, the working frequency range of the radio frequency power amplifier can be 100MHz to 500MHz, the frequency range is divided into 8 sub-bands with the same width, and the width of each sub-band is 50MHz;
step 4.2 and step 4.3 subdivide the values after a/D conversion in each sub-band, for example using a 10 bit a/D converter, with a conversion value in the range 0-1023,
inputting the analog voltage signal output by the detector into an A/D converter to obtain a corresponding digital signal, namely, converting the detected voltage signal into a 10-bit digital value, wherein the range is 0-1023;
the a/D values can be divided into 21 segments in total, each segment containing a range of a/D values (0-50, 51-100,101-150,.. 951-1000,1001-1023);
step 4.4, in each a/D value segment of each sub-band, the corresponding k and b values need to be calculated, in such a segment, the relationship between the output power and the a/D value corresponding to the detector output voltage may be approximately linear, so that it may be ensured that in each segment, the output power may be more accurately calculated using the formula p=kv+b, where P is the output power, the slope k represents the changing relationship between the output power and the a/D value corresponding to the detector output voltage, and the intercept b represents the reference value of the output power when the output voltage is 0;
step 4.5, storing k and b parameters of all A/D value segments of all sub-bands in a data memory, and reading corresponding k and b parameters from the data memory according to the current working frequency and the detected A/D value when the system is powered on, so as to calculate output power and control a radio frequency power amplifier;
through the steps, the output power of the radio frequency power amplifier can be accurately measured and controlled by subdividing the value after the A/D conversion in each sub-band.
In this embodiment, the steps of calculating the k and b values are as follows:
build 1: p1=kv1+b and formula 2: p2=kv2+b, where (P1, v 1) and (P2, v 2) are respectively the actual output power value (P1, P2) in the same range of a/D values in the same frequency band region and the a/D value (v 1, v 2) corresponding to the voltage value at the detector output, the actual output power being measured by a power meter;
the specific calculation process is as follows:
(P1-P2) =k (v 1-v 2), yielding: k= (P1-P2)/(v 1-v 2), and substituting the k value into formula 1 or formula 2;
solving the b value, b=p1-k×v1 or b=p2-k×v2;
after the values of k and b are solved, the values of k and b are stored in the storage areas of the corresponding frequency bands and AD bands which are divided before;
the A/D values of other sections in the same frequency band region and the k and b values in all the A/D value sections in other frequency band regions are calculated by adopting the steps;
when calculating the power value, the k and b values are taken out from the corresponding frequency band region and the AD section where the current AD value is located, and the actual power value is calculated;
the method can find the corresponding k and b values for each A/D value segment of each sub-frequency band, then store the values in a data memory, and read the k and b parameters of all A/D value segments of the corresponding frequency band when the system is powered on, thus calculating the output power of the radio frequency power amplifier according to the detected A/D values and realizing the control of the radio frequency power amplifier.
In this embodiment, the accuracy of the output power measurement of the radio frequency power amplifier is improved through step 4, specifically, the whole frequency band and the a/D value are subdivided, so that the relationship between the a/D value corresponding to the voltage value collected in each frequency band and the output power value is approximately linear, in each subdivided frequency band, the output power can be approximately calculated through a primary function p=kv+b, so that more accurate output power is obtained, and the problem that the amplitude of the output signal detected by the detector at the final stage is different after the input signal with the same amplitude in different frequency bands is amplified by the power amplifier is solved.
In the present embodiment, the actual output power value is used as a reference for calculating the k and b values in step 3.
In this embodiment, the rf power amplifier control system may adjust the operating state of the rf power amplifier according to the output power parameter values so as to maintain its output power within a desired range;
for example, if the output power value is below the desired value, the radio frequency power amplifier control system may increase the output power by adjusting the amplitude of the input signal or adjusting an operational parameter of the amplifier;
conversely, if the output power value is higher than the expected value, the radio frequency power amplifier control system can take opposite measures to reduce the output power, and in this way, the radio frequency power amplifier control system can realize accurate control of the radio frequency power amplifier so as to meet the requirements of different application scenes.
In this embodiment, the width of each sub-band in step 4.1 may be the same or different, specifically:
the sub-band widths are the same: if the frequency response characteristics of the radio frequency power amplifier are relatively uniform over the entire operating frequency range, then the sub-band widths may be selected to be the same;
this has the advantage of simplifying the sub-band division process, facilitating implementation and management, however, this approach may not achieve optimal linearity in certain frequency regions;
the widths of the sub-bands are different: if the frequency response characteristics of the radio frequency power amplifier in different frequency regions are greatly different, the frequency sub-band width can be set to be different;
the method has the advantages that the width of the sub-frequency band can be flexibly adjusted according to the actual requirements and the change of the frequency response characteristic so as to obtain better linearity;
the method can realize higher output power measurement accuracy in a specific frequency region;
in summary, the choice of the sub-band width depends on the actual frequency response characteristics of the rf power amplifier and the application field Jing Xuqiu, in some scenarios the same sub-band width may be sufficient to meet the requirements, while in other scenarios different sub-band widths may contribute to achieving higher measurement accuracy;
for example, assume that an rf power amplifier operates in a frequency range of 100MHz to 500MHz and has a relatively uniform frequency response throughout the operating frequency range;
in this case, the whole frequency band can be divided into sub-frequency bands with the same width, for example, the frequency range is divided into 8 sub-frequency bands with the same width, each sub-frequency band has the width of 50MHz, and the division manner can meet the requirements of most application scenes, such as a communication system, a broadcast, a wireless network and the like;
for another example: assuming that the operating frequency range of a radio frequency power amplifier is still 100MHz to 500MHz, there is a large difference between the frequency response characteristics in some frequency regions (e.g., 200 MHz to 300 MHz) and other frequency regions;
in this case, the entire frequency band may be divided into sub-bands of different widths, for example, the frequency range is divided into 3 sub-bands, the width of sub-band 1 (100 MHz to 200 MHz) is 100MHz, the width of sub-band 2 (200 MHz to 300 MHz) is 100MHz, and the width of sub-band 3 (300 MHz to 500 MHz) is 200 MHz;
the division mode can realize higher measurement accuracy in a specific frequency region, such as a special communication system or radio frequency interference test.
In this embodiment, as shown in fig. 1, the radio frequency signal to be detected outputs an analog voltage through the detector, and is used as an input signal for a/D conversion, the a/D value after conversion is read out by a single chip Microcomputer (MCU), and the a/D value is converted into a power value after calibration and output.
In this embodiment, as shown in fig. 3, the calibration process and the process of calculating the power value according to the current AD value may be parallel processes, and have no influence on each other; if the upper computer performs calibration, the corresponding command interacts with the singlechip, and the singlechip can store the corresponding parameters; the chip may read the corresponding parameter calculation power value from the memory and is always executing.
A radio frequency power amplification control system comprises a radio frequency power amplifier and a data memory for storing k and b parameters of all A/D value segments of all sub-frequency bands of the amplifier, wherein the k and b parameters of all A/D value segments of all sub-frequency bands of the amplifier are obtained by a radio frequency output power calibration method.
A radio frequency output power calibration apparatus comprises a memory for storing a computer program and a processor for implementing a radio frequency output power calibration method when the computer program is executed.
