This paper presents a novel loopback waveguide duplexer, and processing of physical verification. The diplexer features very flat out-of-band suppression to meet the functional needs of self-checking and calibration of electronic systems that simplify the complexity of electronic systems and improve the performance of electronic systems. The diplexer adopts the coupling matrix synthesis design, and the common port adopts the calculation of the port delay design to eliminate the influence of the high-low side filters. The design method is simple and flexible, the calculation is small, the design accuracy is high.
