In this paper, a novel three-port combiner based on coaxial cavity is presented, which consists of a band-pass filter with a transmission zero and a ultra-wideband band-stop filter, and the combiner is different to the conventional combiner based on microstrip or stripline. The design and simulated results show that the novel combiner has a good performance, which are insert loss more than -0.5dB and return loss less than -20dB between the GSM/DCS/TD band (800-2170MHz) and WLAN band (2400-2500MHz), the isolation in both bands less than -85dB, respectively. In addition, the performances of the novel combiner are demonstrated experimentally, the measured results have good agreement with simulated results.

AbstractWe present a new ultra-wideband (UWB) band-pass filter (BPF) configuration with a stepped impedance short-circuited stub (SISS)-loaded triple-mode resonator (TMR) and stepped impedance radial stub (SIRS). The novel SISS-loaded TMR and SIRS improve the roll-off ratio at both ends. Even though this UWB BPF is based on a single resonator, the measured results show excellent in-band performance with a small insertion loss less than 0.6 dB and return loss greater than −16 dB. The proposed UWB BPF has sharp roll-off ratio of 96 and 43 dB/GHz, respectively, at the lower and upper edges of the pass-band, and a wide stop-band from 10.8 to 15.6 GHz with the rejection greater than 20 dB.
