Title
Ku/Ka-band compact orthomode junction with low pass filters for high power applications
Abstract
This paper presents a compact orthomode junction with low pass filters for high power applications. It consists of a circular waveguide step, a matching element for high frequency band and coupling sections straddle the circular waveguide step. These dimensions were optimized to achieve wideband performances and to support a high power rating. The structure without rectangular to circular transition is simple and comprised of two milled layers to divide E-plane of corrugated low pass filters. It can be easily manufactured and has low losses. The fabricated Ku/Ka-band orthomode junction was measured including power handling test of 2kW at Ku-band. The measurement results demonstrated return loss of 21dB and loss of 0.2dB in the Ku- and Ka- band.
