Patent ID: 7957703

Claim:
A wireless circuit device for transmitting and receiving a wireless signal, comprising: an antenna for transmitting and receiving the wireless signal; a transmission circuit for outputting a transmission signal; a reception circuit to which a reception signal is inputted; an antenna duplexer for supplying, to the antenna, the transmission signal outputted from the transmission circuit and for inputting the wireless signal received by the antenna to the reception circuit as the reception signal; a transmission signal control circuit for controlling, by means of a control signal, the transmission signal to be outputted from the transmission circuit; a storage section for storing control information used for controlling current flowing into the reception circuit, the control information comprising, control information representing a non-transmission mode where the transmission circuit transmits no transmission signal and at least two further pieces of control information respectively representing at least two transmission modes where the transmission circuit transmits the transmission signal; and a current control circuit for controlling the current flowing into the reception circuit in accordance with the control information, stored in the storage section, comprising the control information representing the non-transmission mode and the at least two further pieces of control information respectively representing the at least two transmission modes, wherein the current control circuit recognizes whether or not the transmission signal is transmitted based on the control signal outputted from the transmission signal control circuit, controls, when the transmission signal is transmitted, the current flowing into the reception circuit in accordance with one of the two further pieces of control information representing any of the at least two transmission modes, and controls, when no transmission signal is transmitted, the current flowing into the reception circuit in accordance with the control information representing the non-transmission mode.
