The signal VVSW is of a voltage level that is lower than that of the control signal VTRXC. The control signal VTRXC is a signal for turning ON a transistor circuit Q1, and the signal VVSW is a signal for supplying a DC voltage to the antenna potential. It is thereby possible to reduce the ON resistance of the transistor circuit Q1 and improve the IMD characteristics. |
