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 X-band were performed using frequency up-converters. Finally a four channel prototype was built to evaluate the network connectivity of the phase shifter.
