The Design of 220GHz Power Synthesis Circuit Based on 3dB Waveguide Couplers

At present, the development of terahertz applications is mainly limited by the generation of terahertz waves. In order to meet the needs of high power sources, a comprehensive research of 220GHz power synthesis circuit based on 3dB waveguide couplers has been presented in this paper, which includes two branch waveguide couplers and two 220GHz solid-state multipliers. Both the branch waveguide couplers and the multipliers show the great simulation performance according to the Ansoft HFSS electromagnetic simulator.
