Phase shifter system using vector modulation for xband phased array radar applications

摘要

This paper presents the design and implementation of a complete phase shifter system using vector (polar) modulation, suitable for solid-state phased array radar applications, providing a cost effective solution which overcomes the main constraints involved with traditional systems. The performance characteristics for three intermediate frequencies were measured. In addition, measurements at Xband were performed using frequency up-converters. Finally a four channel prototype was built to evaluate the network connectivity of the phase shifter.
