Abstract
A high-frequency switch 20 includes a first diode 24. An anode of the first diode 24 is connected to a transmitting circuit TX via a capacitor 22, and is grounded via a first strip line 26 and a capacitor 28. A first control terminal 30 is connected to a connecting point of the first strip line 26 and the capacitor 28, and a control circuit for switching the high-frequency switch is connected to the first control terminal 30. A cathode of the first diode 24 is connected to an antenna ANT via a capacitor 32. One end of a second strip line 40 is connected to the antenna ANT via the capacitor 32. The end of the second strip line 40 is grounded via a capacitor 42. The other end of the second strip line 40 is connected to a receiving circuit RX via a capacitor 44, and is grounded via a second diode 46 and a capacitor 48.
