Research on impact factor of the HPA power synthesizes

Cheng Gang, Dai Chao, Liu Shuai China Satellite Maritime Tracking and Control Department, Jiangyin, 214431, China Abstract: In aerospace measurement and control systems, solid-state power amplifier as an important part of the monitoring and control stations for the monitoring station to launch the carrier to provide high enough power to meet the required system EIRP. In this paper, the basic concept and principle of the transmission line are analyzed, and the method of solving the problem is put forward according to the actual situation of the solid state power amplifier of the transmitting sub system: 1). Based on the transmission line impedance matching technology, the transmission line impedance mismatch problem is solved. 2). Add phase shift components, to solve the transmission line between the phase match inconsistencies.
