AI Technical Summary
Existing microwave amplifier output power detection schemes are susceptible to output mismatch when the load condition changes, resulting in fluctuations in power characterization. Furthermore, online calibration updates are lagging, affecting the comparability and reliability of the detection results.
By initializing the microwave amplifier, locking the operating conditions, generating the detection disturbance control sequence and the switching trigger pulse sequence, performing direction self-check, establishing the dimensional calibration relationship, obtaining the current steady-state threshold and the temperature steady-state threshold, constructing the steady-state judgment value, calculating the output power, and performing dynamic correction under the dimensional calibration relationship update trigger condition.
It achieves accurate estimation of mismatch intensity and calculation of forward amplitude under steady-state conditions, suppresses operating point drift, maintains output smoothness and stability of protection judgment, avoids accumulation of dimensional drift, and improves the reliability of detection results.
