前端模块具有低插入损耗

Front-end module having low insertion loss
Abstract:
One object is to provide a front-end module with a shared output terminal wherein an input impedance is readily matched and an insertion loss is suppressed. In accordance with one aspect, the front-end module 10 includes an input terminal, output terminals, a first filter circuit that passes signals in a first passband, a second filter circuit that passes signals in a second passband, a switch that is disposed between the input terminal and the first and second filter circuits and selectively connects the input terminal to the first and second filter circuits, and a matching circuit. The second filter circuit includes phase shifters.
