The Design and Estimation of Stability for Phased Array RF System

The phased array antenna has high reliability and becomes a key research point for radar application. The core of the phased array antenna is microwave RF system, including the T/ R module and time-delay amplification module. The T/R module must meet the demand of high efficiency, high amplitude- phase stability, high reliability, low cost, miniaturization and lightweight. These modules always provide high gain and miniaturization simultaneously. So, the design and estimation of RF stability are very important. In this paper, the estimation and design method of stability are discussed. The designed T/R module is stable and reliable for active phased array radar application.
