Abstract
A high frequency front-end module includes an antenna terminal ANT, a diplexer, high frequency switches, LC filters, and SAW duplexers. The SAW duplexer is defined by SAW filters and high-pass filters disposed at input sides thereof. The high-pass filters function as phase-matching elements having an anti-surge function against a surge coming from the antenna terminal ANT.
