Abstract:Large power microwave nonlinear effects on amplitude-phase controller chip were experimentally tested and theoretical analyzed. This chip had the typical application on Ka-band phased array radar (PAR) transmit/receive (T/R) modules. The test platform was built up by a solid source and a pulsed magnetron to generate large power Ka-band microwave. The degradation and destroy phenomenon were observed distinctly as the input power amplitudes were 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 theoretically analyzed.
