Abstract:
1. A radio device comprising: a differential antenna that has a pair of differential power supply terminals; a transmitter that transmits a first signal via the differential antenna; a receiver that has a pair of differential input terminals and receives a second signal via the differential antenna; a first switch unit that switches a signal conduction state and a signal block state between one of the differential input terminals and one of the differential power supply terminals; a second switch unit that switches a signal conduction state and a signal block state between the other of the differential input terminals and the other of the differential power supply terminals; a first control unit that controls the first switch unit and the second switch unit such that the signal block state is caused when the transmitter transmits the first signal; and a second control unit that switches either the first switch unit or the second switch unit from the signal conduction state to the signal block state when the second signal is being received.
