<p>A high frequency switching device (100) includes a control terminal (105), a power source terminal (104), a GND terminal (106), a RF terminal (101), a switch section (110), a control section (130), and protecting diodes (165,166,167). The switch section (110) switches input/output routes of an RF signal input from the RF terminal. The control section (130) controls the switch section (110), and is connected to the control terminal (105) and the power source terminal (104). The protecting diodes (165,166,167) are provided between the control terminal (105) and the RF terminal (101), between the control terminal (105) and the GND terminal (106), and between the power source terminal (104) and the GND terminal (106).
