Abstract :
A programmable phase shifter has been designed and used in a dielectric multistate reflectometer (DMR), which gives a flat relative phase shift over the entire frequency range from 110 GHz up to 170 GHz. It consists of an eccentric rotating cylinder, adjacent to a dielectric guide, which is driven by a stepping motor. The paper describes the performance of the phase shifter used in a DMR.
