T/R module are the core components of communication systems,and the receiver channel in the T/R module often face strong interference signals from the outside environment in operation.Strong external interference signals are an important factor affecting the reliability of T/R module.Therefore,this paper establishes a test platform for over-excitation testing of T/R module and conducts over-excitation tests on T/R module.It also uses metallographic microscopes and focused ion beam(FIB)failure analysis techniques to conduct failure analysis on the T/R module after the test.Based on the test results,the failure locations,failure modes,and failure mechanisms of the receiver channel in the T/R module under over-excitation are determined.The test verifies the anti-interference,power resistance,and burnout resistance of typical T/R module,and provides reference and guidance for the power resistance and burnout resistance design of T/R module.
