Abstract
A radio communication device includes a radio transmitting unit that generates a transmission signal containing a transmission carrier, a radio receiving unit including a frequency conversion circuit that performs down-conversion of a received signal containing a received carrier with substantially equal frequency to the transmission carrier, a transmission/reception separating circuit including a first port connected to the radio transmitting unit, a second port to the radio receiving unit and a third port to an antenna, that outputs the transmission signal into the first port to the third port and the received signal into the third port to the second port, and a transmission power control unit that performs control related to a transmission power of the transmission signal based on a low-frequency signal obtained by supplying a leakage component of the transmission signal leaking from the first port to the second port to the frequency conversion circuit and down-converting it.
