Abstract

A stub switched phase shifter, which consists of a reference line, a delay stub and fewer RF switches than the switched line phase shifter, is proposed. It has low phase deviation characteristics. Especially, for the condition of /spl Phi/=180/spl deg/, S=0, L=1/2/spl lambda/g/sub 0/, the proposed phase shifter can reduce two RF switches, and is as compact as about 40% the size of a conventional switched-line phase shifter. It is suitable for phased array applications. The characteristics of the proposed phase shifter designed for /spl Phi/=90/spl deg/, 180/spl deg/ were confirmed by the method of moments.
