[0018] Embodiment 1: A method for adjusting the output power of a TR module is proposed, such as Figure 1 As shown, the following steps are included:

[0019] Step 1: Monitor the current working status of the TR module.

[0020] Step 2: Determine whether the TR module is currently working. If the TR module is not currently working, execute step 3; if the TR module is currently working, execute steps 4.1 to 4.3.

[0021] Step 3: Return to step 1 without adjusting the output power of the TR module.

[0022] Step 4.1: Collect the RF signal output by the TR module.

[0023] Step 4.2: Collect the ambient temperature of the TR module.

[0024] Step 4.3: Get the working status of the TR module.

[0025] Step 5.1: Convert the RF signal to a power level, and convert the power level to the actual RF power of the TR module.

[0026] Step 5.2: Obtain the standard RF power of the TR module according to the ambient temperature of the TR module and the working state of the TR module.

[0027] Step 6: Obtain the difference between the actual RF power and the standard RF power.

[0028] Step 7: Determine whether the difference between the actual RF power and the standard RF power meets the RMS value range. If yes, go to step 8; if not, go to step 9.

[0029] Step 8: Return to step 1 without adjusting the output power of the TR module.

[0030] Step 9: Obtain a power supply voltage control signal according to the difference between the actual RF power and the standard RF power.

[0031] Step 10: The supply voltage control signal adjusts the output power of the TR module and returns to step 1.

[0032] In summary, the method for adjusting the output power of the TR module proposed in this embodiment monitors the working state of the TR module and the power level of the output RF signal, combines the real-time data of the ambient temperature and the working state, determines whether the output power meets the standard range, adjusts the power supply voltage to correct the power deviation when necessary, and dynamically adjusts the power supply voltage of the TR module, thereby achieving precise control of the output power.

[0033] Embodiment 2: Corresponding to Embodiment 1, this embodiment proposes a system for adjusting the output power of a TR module, including:

[0034] 1. FPGA chip, including the following functional modules:

[0035] TR monitoring module: used to monitor whether the TR module is currently working.

[0036] The first control module: controls the TR monitoring module to work when the TR module is not working, and controls the signal acquisition module to work when the TR module is working.

[0037] Signal processing module: used to convert the power level corresponding to the RF signal output by the TR module into actual RF power, and obtain the standard RF power based on the ambient temperature and working status.

[0038] The first data processing module is used to determine whether the difference between the actual RF power and the standard RF power meets the RMS value range.

[0039] The second control module: when the difference meets the RMS value range, the TR monitoring module is controlled to work; when the difference does not meet the range, the second data processing module is controlled to work.

[0040] The second data processing module is used to obtain a power supply voltage control signal according to the difference.

[0041] The power supply module is used to adjust the power supply voltage according to the power supply voltage control signal, so as to correct the output power of the TR module.

[0042] The FPGA chip also includes: a third control module, which is used to control the TR monitoring module to work after the power supply module sends the power supply voltage to the TR module.

[0043] In another possible implementation, the system further includes:

[0044] Signal acquisition module: used to collect the RF signal output by the TR module.

[0045] Signal conversion module: used to convert RF signals into power levels.

[0046] Temperature acquisition module: used to collect the ambient temperature of the TR module.

[0047] Status acquisition module: used to obtain the working status of the TR module, including the transmitting status or the receiving status.

[0048] Through the coordinated work of the above modules, real-time monitoring and dynamic adjustment of the output power of the TR module can be achieved.

[0049] The working principle of this system is as follows: adopting the closed-loop control principle, with FPGA chip as the core, collecting the RF signal and temperature data of the TR module, and converting them into power levels through AD sampling circuits. FPGA calculates the standard RF power based on temperature data and module status, and compares the difference with the actual power. If the difference exceeds the allowable range, FPGA generates a new power supply voltage control signal and transmits it to the power supply module to correct the output power of the TR module. Through high-speed periodic acquisition and real-time adjustment, the system can continuously maintain the stability of the output power.

[0050] Effective effects include: Accuracy: Closed-loop control is adopted to adjust power in real time, which significantly improves control accuracy and system stability. Efficiency: High-speed acquisition and computing power reduce response delay and improve adjustment efficiency. Adaptability: Optimize power output in combination with ambient temperature and working status to adapt to diverse working environments. Simplify process: Avoid the complexity and high cost of the rework process and simplify the phased array antenna test process. Reliability: Through real-time monitoring and adjustment, power fluctuations are effectively reduced and system reliability is improved.

[0051] Alternative or modified embodiments:

[0052] First, adaptability to different environments. Under extremely high or low temperature conditions, the RMS value range can be adjusted to meet different environmental requirements.

[0053] Second, algorithm optimization: Replace the internal algorithm of FPGA, for example, introduce AI model to optimize power calculation accuracy.

[0054] Third, hardware upgrade: Use higher performance AD ​​sampling circuits or power supply modules to further improve adjustment speed and power stability.

[0055] By combining the above embodiments, the present invention can maintain stable and efficient power adjustment capabilities in a wide range of application scenarios.

[0056] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
