Abstract :
This paper demonstrates the bandwidth limitation of a multiplexer imposed by the poor stopband performance of standard E-plane filters. Bandwidth improvement is achieved introducing ridge waveguide filters in the multiplexer. A four-channel X-band E-plane manifold multiplexer is used as an example. Electromagnetic modelling of the multiplexer and experimental verification of ridge waveguide filter are presented.
