Disclosed is a fabrication method for miniaturizing a film bulk acoustic wave resonator (FBAR) duplexer module including two FBAR filters, a tuning inductor, and a phase shifter. An exemplary embodiment of the present disclosure provides a method of miniaturizing a FBAR duplexer module, including forming a tuning inductor in a multilayer printed circuit board (PCB), forming a phase shifter in the multilayer PCB, and forming at least one of a transmitting FBAR filter and a receiving FBAR filter in the multilayer PCB. |
