<p>PROBLEM TO BE SOLVED: To provide a high-frequency signal switching device which can more effectively remove higher harmonic components generated by a switching element. SOLUTION: This high-frequency signal switching device is provided with a transmission input terminal TX, a reception output terminal RX, and an antenna terminal ANT. The switching device is also provided with a switching means, which switches the connecting destination of the antenna terminal ANT between the transmission input terminal TX and reception output terminal RX, a transmission-side matching circuit MT, which is provided between the input terminal TX and antenna terminal ANT and matches the impedance between the terminals TX and ANT, and a reception-side matching circuit MR, which is provided between the output terminal RX and antenna terminal ANT and matches the impedance between the terminals RX and ANT.</p> |
