abstract = {This document describes the design of a phase switch with four states intended for a radio astronomy receiver which operates in the 35-47 GHz frequency band. The phase switch has two microwave branches which are combined by a Wilkinson divider/combiner. Each branch is based on a 180º phase switch connected in cascade with a different band-pass filter. The phase shift between the two band-pass filters is 90º. The switching devices are microwave PIN diodes. Experimental results have shown average phase shift values of 178º and 87.3º within the operation band for the phase switch and the bandpass filters respectively. The complete phase-switch have been validated by simulations of the cascaded elements including the
Wilkinson combiner/divider.},
