Measured Characteristics of Variable Power Dividers

Abstract

A multiple-beam antenna system for Defense Satellite Communication System satellites offers an increased flexibility in controlling pattern shape for the suppression of interfering signals as well as providing narrow high-gain beams. One method of controlling the patterns of such an antenna system is to use a beam-forming network consisting of variable power dividers which are electronically controlled. It is then of interest to determine the characteristics of these power dividers. This note presents some measured characteristics of a particular variable power divider that uses non-reciprocal, latching, ferrite phase shifters to obtain electronic control of the amplitude at each of the beam ports of a multiple-beam antenna system.
