%X a wideband diplexer in waveguide technology is designed to demonstrate the feasibility of using stepped waveguide junctions for diplexer designs. it consists of a channel filter, a low pass filter and a t e-plane junction. to validate the previous concepts, a c-band diplexer was constructed and tested using conventional milling techniques. the relative bandwidth of the whole diplexer is about 64%. the inputs and outputs return losses were less than 23db, the isolation is better than 60db 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.
