Ka波段相控阵雷达TR组件幅相控制芯片的大功率微波非线性效应研究
Investigation of large power microwave nonlinear effects on amplitude-phase controller chip for Ka-band phased array radar T/R modules
摘要
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.关键词
