Abstract:This paper presents the design of a compact size, passive, W to K band subharmonic mixer with post-wall waveguide (substrate integrated waveguide) RF input interface. The mixer is based on a silica-glass structure where the post-wall waveguide and microstrip line are on separate substrates. This configuration maximizes the performance as the substrate thicknesses can be separately optimized for the lowest loss and mono-mode operation. Integration of different types of guiding structures also allows realization… Show more
