The problem that the electromagnetic interference(EMI) between the functional modules has become more and more significant with the development of the integration level and complexity of T/ R module. EMI could result in the performance degradation and function errors of T/ R modules, and even the circuits damage leading to the fatal influence to the RADAR in extreme situations. Therefore the EMI issue should be attached importance to in the preliminary stage of T/ R module design. Presented here are representative issues and solutions of EMI problems in T/ R module designing. Also the principles of T/ R module design aiming at reducing the damage resulting from EMI issues are illustrated.
