'See-saw' phase shifter cuts cost of phased array
Abstract
A 'see-saw' phase shifter design is described which has been shown to significantly reduce the cost of phased radar array components. This design involves a unique four-port network which controls the differential phase delay in two signal paths simultaneously. The network is described and the practical design problems of the network are addressed. The special design difficulties that occur when there is a broadband requirement are considered, and the improvement of the design by the elimination of PIN diodes is discussed.
