Abstract

A compact high-frequency module that increases isolation between a transmission-side circuit and a reception-side circuit of a duplexer includes a switch element and duplexers. The duplexers include transmission-side SAW filters and reception-side SAW filters. The transmission-side SAW filters are mounted near one edge of a multilayer body. The reception-side SAW filters are mounted near another edge opposite to the one edge of the multilayer body. The switch element is mounted at the center of the multilayer body.

First claim

What is claimed is:

1. A high-frequency module comprising:
a switch element arranged to selectively connect a plurality of individual terminals to a common terminal;
a duplexer arranged to demultiplex a transmission signal and a reception signal in a single communication band; and
a multilayer body including the switch element and the duplexer amounted on a top surface of the multilayer body, electrodes for external connection ports provided on a bottom surface of the multilay…
