Abstract:Large power microwave nonlinear effects on amplitude-phase controller chip are experimentally tested and theoretical analyzed. This chip has the typical application on Ka-band phased array radar (PAR) transmit/receive (T/R) modules. The test platform is built up by a solid source and a pulsed magnetron to generate large power Ka-band microwave. The degradation and destroy phenomenon are observed distinctly as the input power amplitudes are improved. The total-state phase characteristics and the degradation thresholds of the selected chip are obtained through a series of experimental tests. At last, the results are given by figures and the damage mechanism is analyzed theoretically.
