Abstract
An RF signal transmitting/receiving circuit includes: at least one power amplifier circuit that amplifies and outputs an RF transmission signal; duplexers each including a transmission filter that passes the RF transmission signal amplified by the power amplifier circuit, and a reception filter that passes an RF reception signal; at least one distribution circuit that divides the RF transmission signal input to the power amplifier circuit and outputs a first signal; a signal output circuit that outputs, based on the first signal, in at least one transmission path among transmission paths of a plurality of the RF reception signals, at least one second signal that has substantially a same delay amount, an inverted phase, and substantially same power as the RF transmission signal mixed in the RF reception signal; and coupling circuits that couple the second signal to the RF reception signal transmitted in the at least one transmission path.
