In a radio frequency circuit for multi-mode operation on which multiple transceivers complying with multiple communication systems are disposed, signal interference between circuits is reduced. The PA 222, and the output matching networks 223a and 223b of GSM system, which are circuits independent of the circuit operation of W-CDMA, are disposed in a section of the shortest distance between the PA 121 that handles RF transmission signals of W-CDMA being a first communication system, a third output matching network and an isolator, and a receiver that handles RF received signal of W-CDMA, and in a section of the shortest distance between the PA 121 and the transmitter 130 of W-CDMA. The PA 222, which is a circuit independent of the circuit operation of W-CDMA, is disposed in a section of the shortest distance between the PA 121 and the inter stage filter 125 of W-CDMA.
