Abstract
This paper describes lightweight GFEC 4 GHz multiplexer, consisting of dual mode quasi elIiptic fiIters mounted on a waveguide manifold. These filters are for use in communications satelIites to meet the high performance requirements with state-of-the-art technology. Experimental results of a typical channel are given, and spurious performance of these filters is discussed. Thermal results of the filters indicate an average frequency shift of about 0.5 MHz over 50/spl deg/C.
