A new design of microstrip power-divider (PD) diplexer with simple layout is presented. The proposed design is directly formed up by two independently designed dual-mode filtering PDs without any additional matching network at the common port, thus bringing significant design flexibility and size reduction to the design process. For validation, a prototype PD diplexer working at 2.45 and 2.98 GHz is finally implemented and measured. Measured results agree well with the simulated ones. Results indicate that the PD diplexer exhibits sharp passband selectivity, good port-to-poll isolation and high channel isolation, which is very attractive for applying to the multi-standard wireless coiruntmication systems.
