Abstract

The directional coupler is a kind of microwave component, which has been widely used in the microwave field, and is mainly used in signal isolation, mixing and separation. The directional coupler is a combination of transmission lines directly. This design mainly uses ADS software to design a high-coupling microstrip branch directional coupler, and completes circuit simulation and layout simulation in ADS software. The designed high-coefficient microstrip branching directional coupler has a center frequency of 2.45 GHz. The simulation results are characterized by an isolation of -44.9 dB in the center band and a coupling degree of -3.05 dB in the center band.
