Description

Technical Field

[0001] The present invention relates to the technical field of phased array antenna gain compensation, and in particular to an adaptive receiving gain compensation method and system. Background Art

[0002] High-density silicon-based millimeter-wave phased array antennas have small circuit size, dense array, and high power consumption, which causes the antenna array surface to heat up rapidly. In the absence of good heat dissipation methods, as the temperature rises, the performance of the millimeter-wave RF transceiver chip deteriorates and the antenna reception gain decreases significantly.

[0003] Currently, most RF transceiver circuits use a current bias proportional to the temperature of the millimeter-wave RF transceiver chip to compensate for the decrease in the transceiver chip's receive gain as temperature rises. However, this method not only produces a small gain compensation, but often fails to meet requirements and cannot accurately compensate for the decreased gain. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the traditional technology used to compensate for the antenna receiving gain cannot accurately compensate for the decreased receiving gain. The purpose is to provide an adaptive receiving gain compensation method and system. According to the transceiver chip operating within the allowable voltage range, increasing the voltage can improve the antenna receiving gain. This solution adaptively adjusts the transceiver chip voltage through a function mapping relationship based on the change in the temperature sensor when the antenna is working, thereby solving the problem that the traditional technology cannot accurately compensate for the antenna receiving gain.

[0005] The present invention is achieved through the following technical solutions:

[0006] An adaptive receiving gain compensation method, the method comprising the steps of:

[0007] S1: The computer records the data of the RF transceiver chip receiving gain changing with temperature at room temperature;

[0008] S2: The computer fits the recorded data to generate a first function of how the receiving gain changes with temperature, and transmits the function to the voltage control module;

[0009] S3: The computer records data on how the receiving gain of the RF transceiver chip changes with the operating voltage at room temperature;

[0010] S4: The computer fits the recorded data to generate a second function of how the receiving gain changes with voltage, and transmits the function to the voltage control module;

[0011] S5: The voltage control module calculates the attenuation of the receiving gain by substituting the temperature change value of the RF transceiver chip measured by the temperature sensor into the first function;

[0012] S6: The voltage control module brings the attenuation of the receiving gain into the second function to calculate the voltage increase;

[0013] S7: The voltage control module adjusts the operating voltage of the transceiver chip according to the voltage increase, thereby increasing the receiving gain of the RF transceiver chip.

[0014] In this solution, a millimeter-wave RF transceiver chip is used in a high-density silicon-based millimeter-wave phased array antenna, so the above-mentioned RF transceiver chip is a millimeter-wave RF transceiver chip.

[0015] The RF transceiver chip is powered on and operates continuously at room temperature, and a computer records data on how the chip's receiving gain changes with temperature. The computer fits the recorded discrete data to generate a first function, where the first function has temperature as an independent variable and the transceiver chip's receiving gain as a dependent variable. The computer transmits the fitted first function to a voltage control module.

[0016] At room temperature, within the allowable operating voltage range of the transceiver chip, the operating voltage is gradually increased in steps, and the computer records data on how the receiving gain of the transceiver chip changes with the current voltage; the computer fits the recorded discrete data to generate a second function, where the second function has the voltage as an independent variable and the receiving gain of the transceiver chip as a dependent variable, and the computer transmits the fitted second function to the voltage control module;

[0017] The voltage control module calculates the attenuation of the receiving gain by substituting the temperature change value of the RF transceiver chip measured by the readback temperature sensor into the first function. The calculated attenuation of the receiving gain is then substituting into the second function to calculate the voltage increase. The voltage control module adjusts the operating voltage of the transceiver chip according to the voltage increase, and adds the voltage increase to the original operating voltage of the transceiver chip. For example, if the initial operating voltage is V0 and the voltage increase is ΔV, the operating voltage of the transceiver chip is changed to V=V0+ΔV.

[0018] To summarize, the first function and the second function are generated by repeated test records and fitting. According to the change of the temperature sensor when the antenna is working, the voltage increase is calculated through the mapping relationship between the first function and the second function. The voltage control module adaptively adjusts the voltage of the transceiver chip according to the calculated voltage increase, which solves the problem that traditional technology cannot accurately compensate for the antenna receiving gain, and realizes dynamic compensation for the attenuation of the receiving gain of the RF transceiver chip caused by increasing temperature.

[0067] S4: The computer fits the recorded data to generate a second function of the receiving gain varying with voltage, and transmits the function to the voltage control module 1;

[0068] S5: The voltage control module 1 calculates the attenuation of the receiving gain by substituting the temperature change value of the RF transceiver chip measured by the temperature sensor 4 into the first function;

[0069] S6: The voltage control module 1 brings the attenuation of the receiving gain into the second function to calculate the voltage increase;

[0070] S7: The voltage control module 1 adjusts the operating voltage of the transceiver chip according to the voltage increase, thereby increasing the receiving gain of the RF transceiver chip.

[0071] In a specific embodiment, a millimeter-wave RF transceiver chip is used in a high-density silicon-based millimeter-wave phased array antenna. Therefore, the above-mentioned RF transceiver chip is a millimeter-wave RF transceiver chip. The above-mentioned millimeter-wave RF transceiver chip is ANDAR's ADT2011, with an operating bandwidth of 76-81GHz. As the operating temperature of the chip increases, the receiving gain will decrease rapidly, and then the gain will gradually stabilize.

[0072] The RF transceiver chip is powered on at room temperature t0 and works continuously for T minutes. The computer records the chip's receiving gain G r1 Data that changes with temperature t; the computer generates the first function G after fitting the recorded discrete data r1 (t), the first function G r1 (t) With temperature as the independent variable and the receiving gain of the transceiver chip as the dependent variable, the computer transmits the fitted first function to the voltage control module 1;

[0073] At room temperature t0, within the operating voltage range of the transceiver chip, the operating voltage is gradually increased in steps. The above computer records the receiving gain G of the transceiver chip. r2 The data changes with the current voltage V; the computer generates a second function G after fitting the recorded discrete data r2 (V), the second function takes voltage as an independent variable and the receiving gain of the transceiver chip as a dependent variable, and the computer transmits the fitted second function to the voltage control module 1;

[0074] The voltage control module 1 calculates the attenuation ΔG of the receiving gain by substituting the temperature change value of the RF transceiver chip measured by the readback temperature sensor 4 into the first function. The calculated attenuation ΔG of the receiving gain is then substituted into the second function to calculate the voltage increase ΔV. The voltage control module 1 adjusts the operating voltage of the transceiver chip according to the voltage increase. The initial operating voltage is V0, the voltage increase is ΔV, and the operating voltage of the transceiver chip is changed to V=V0+ΔV.

[0075] The temperature information fed back in real time by the temperature sensor 4 is used by the voltage control module 1 to calculate the gain attenuation, and then the setting value of the millimeter wave RF transceiver chip voltage is obtained. By increasing the transceiver chip voltage, the antenna receiving gain is correspondingly increased, thereby maintaining the antenna receiving gain in a stable state and achieving the effect of adaptive receiving gain compensation.

[0076] In a specific embodiment, the RF transceiver chip is powered on at room temperature and works continuously for T=2 minutes. The curve of receiving gain changing with temperature is as follows: Figure 4 As shown above, the RF transceiver chip is at room temperature, and the initial operating voltage starts from V0 = 1.2V, and V s =0.05V is a step to gradually increase the operating voltage, where the receiving gain changes with the operating voltage curve as shown in Figure 5 As shown; normal temperature t0 = 26.5 ° C, according to the measured antenna receiving gain G r The curve that changes with increasing temperature t can be used to obtain the first curve fitting function:

[0077] G r1 (z)=p1*z 8 +p2*z 7 +p3*z 6 +p4*z 5 +p5*z 4 +p6*z 3 +p7*z 2 +p8*z+p9;

[0078] in,

[0079] The correlation coefficients are as follows:

[0080]

[0081] Normal temperature gain

[0082] Initial voltage V0 = 1.2V, measured antenna receiving gain G r2 It is linearly related to the current working voltage V of the RF transceiver chip. s=0.05V, the antenna receiving gain increases by 1dB, and the second functional relationship is:

[0083] G r2 (V) = 20·V + 11;

[0084] When the antenna is first powered on, the initial operating voltage of the millimeter-wave RF transceiver chip is V0, and the gain at room temperature is G0. As the antenna continues to operate, the temperature sensor 4 transmits the current temperature information t = 30°C in real time, so the current gain attenuation can be calculated as:

[0085]

[0086] The gain is compensated by increasing the operating voltage of the transceiver chip. According to the voltage-gain function, the voltage increase is:

[0087] ΔV=ΔG20=0.205V;

[0088] The voltage control module 1 sets the operating voltage of the millimeter wave RF transceiver chip to:
