Abstract :
In this paper, a coupled resonator waveguide diplexer operating in frequency range 11.5-14 GHz is presented. The diplexer structure consists of a waveguide E-plane T-junction and two waveguide cavity filters whose center frequency are 12.375 GHz and 13.125 GHz. The simulation results show that over the operating band of the two filters the return loss is better than -18 dB and the the insertion loss is lower than 0.05 dB. the out-band rejection is higher than 30 dB at the suppression frequency band of 11.75 GHz to 12 GHz and 13.5 GHz to 13.75 GHz.
