Abstract

This article describes a novel phase linear, sharp & symmetrical roll-off, ultra-wideband, contiguous, planar diplexer using Suspended Stripline (SSL) technology implemented on RO5880 dielectric material. The lowpass and highpass channels cover wide bandwidth of DC-35GHz and 35GHz-65GHz respectively. The synthesis, design and simulation of the diplexer is done using closed form analytical model in AWR´s iFilter. Final design of the diplexer is optimized using CST a 3D EM simulator.
