A brief and practical method of H-plane waveguide diplexer design is introduced. For the issue of the harmonic of the low frequency filter in the high frequency filter, the method of preload is mentioned. A new structure three-port junction is designed for the diplexer with the band between the passband of two filters is wide. The integer optimize method of diplexer is introduced. The diplexer, in this literature, with the center frequency 21GHz and 29.5GHz and bandwidth 300MHz. The restrain excel -120dB and -65dB respectively.
