Abstract:
1. A high-frequency switch module comprising a high-frequency switch circuit common to high-frequency signals of a plurality of frequency bands comprising said high-frequency switch circuit, comprising: first and second filter circuits connected to an antenna terminal and having different passbands from each other; a first high-frequency switch connected to said second filter circuit for switching a signal path for passing a transmitting signal of a first frequency band and a transmitting signal of a second frequency band, and a signal path for passing a received signal of said first frequency band and a received signal of said second frequency band; and a branching circuit connected to said first high-frequency switch for passing one received signal in said first and second frequency bands but blocking the other received signal, wherein said high-frequency switch circuit is formed in a laminate having terminal electrodes formed on one surface thereof.
