This paper will discuss implementation of several planar and non-planar ultrabroad band contiguous and non-contiguous diplexer designs at millimeter wave frequencies up to 100 GHz . The diplexers discussed are realized using suspended stripline (SSL) or combination of SSL and E-plane waveguides. These diplexers meet stringent performance requirements for applications such as broadband signal acquisition systems (real-time oscilloscopes) and at component level application such as millimeter wave mixers where frequency splitting is required for IF and LO. The system level performance parameters include symmetrical steep band selectivity with low in band insertion loss. Also maintaining better than 12dB return loss and phase linearity at the crossover frequencies which becomes difficult at millimeter waves above 30GHz. The paper will also highlight use of organic Liquid Crystal Polymer dielectric material for design of contiguous diplexers up to 100GHz on planar SSL technology.
