A X-Band Tunable Diplexer based on Talbot Effect

Based on the principle of talbot effect, a X-band tunable high power diplexer is studied, which adopts bridge and phase shifting. The good isolation ability between such bridge ports is used to achieve dual frequency power synthesis, which can replace the filter structure in the traditional diplexer. The simulation results with Ansoft HFSS shows that the transmission efficiency of the tunable interferometer are more than 97% in the frequency band from 9.2GHz to 10GHz, and the power capacity can reach GW level. Which would be applied in the high power microwave system, through the seveal ways power synthesis, and the system whole power capacity can reach tens of GW.
