Optimization design of phase characteristics of RF transceiver module in radar system

Phase linear characteristic is an important parameter of RF transceiver module in phased array radar system. This paper analyzes the causes of phase nonlinear based on the mechanism of which, and puts forward four methods of optimizing the phase linear. Finally, an X-band RF transceiver module is designed and manufactured to verify the effectiveness of the methods. The test results show that by using the methods proposed, the phase distortion of the RF transceiver module can be improved obviously.
