Abstract :
A novel topology for designing 60 GHz duplexers is presented. Both the receiver (Rx) and transmitter (Tx) filters of the duplexer, which were constructed using dual-mode substrate-integrated waveguide (SIW) cavities, can exhibit a single-sided transmission zero. The transmission zeros were arranged to achieve high channel isolation and frequency selectivity. The results confirm that the fabricated duplexer can achieve an Rx/Tx isolation higher than 30 dB.
