A wideband diplexer is designed and constructed to demonstrate the feasibility of using stepped waveguide junctions for diplexer designs. It consists of two channel filters and a Tee E-plane junction. The relative bandwidth of the whole diplexer is about 64%. Two versions of this device has been constructed and tested in the C-band. The inputs and outputs return losses were less than -25dB, the isolation is > 80dB and the transmission loss was 0.1dB. Moreover, a manufacturing tolerance has been taken into account at the design step, and therefore, the designed diplexer need not be tuned after manufacture.
