Abstract:
A high-frequency module includes a GaAs switch defining an FET switch for selectively connecting one of four RF input-output terminals to an antenna input-output terminal to be connected to an antenna. A GSM transmission signal input terminal is connected to the RF input-output terminal of the GaAsSW through a low-pass filter, and a DCS/PCS transmission signal input terminal is connected to the RF input-output terminal through a low-pass filter. A GSM 850 reception signal output terminal and a PCS reception signal output terminal are connected to the RF input-output terminal through a diplexer, and a GSM 900 reception signal output terminal and a PCS reception signal output terminal are connected to the RF input-output terminal through a diplexer.
