A high-frequency switch module (10) comprises a switch IC (100), a phase adjustment circuit (200), and a filter circuit (300). The phase adjustment circuit (200) comprises an inductor (201) and capacitors (202, 203) and is formed from a &pgr; circuit, wherein the inductor (201) is serially connected between an individual terminal (111) and the filter circuit (300). The filter circuit (300) is an LC parallel resonator circuit of a filter inductor (301) and a filter capacitor (302). A distortion secondary high-frequency signal from the individual terminal (111) of the switch IC (100) is reflected with the filter circuit (300) via the phase adjustment circuit (200), and returns to the switch IC (100) via the phase adjustment circuit (200). This distortion secondary high-frequency signal is phase adjusted by the phase adjustment circuit (200), and is offset with a distortion secondary high-frequency signal which is outputted by a common terminal (101) of the switch IC (100). |
