Abstract :
A new millimetre-wave integrated diplexer arrangement is introduced utilizing metal insert channel filter technology and H-plane waveguide matching configurations. Due to a rigorous and efficient field theory method, special waveguide transformer sections are optimized which compensate for field distortions within the filter bandwidths. Since higher-order mode interactions are advantageously taken into account, the design is suitable for millimetre-wave applications requiring no additional fine-tuning elements. Computer-optimized design data are presented in the Ka- and W-band frequency range.
