High-frequency switch module |
摘要 |
A high-frequency switch module includes a first switching element and a second switching element. A common terminal of the first switching element is connected to an antenna. A common input terminal of the second switching element is connected to a multi-band power amplifier. A second individual output terminal of the second switching element is connected to a fourth individual terminal of the first switching element via a first low-pass filter, and is connected to a third individual terminal of the first switching element via a series circuit including a second low-pass filter and a high-pass filter. A first individual output terminal of the second switching element is connected to a first individual terminal of the first switching element via a phase-shift circuit and a first SAW duplexer, and is connected to a second individual terminal of the first switching element via the phase-shift circuit and a second SAW duplexer. |
