The present invention discloses a dual-band RF transceiver. The transceiver comprises a first module, used as the RF front-end of the dual-band transceiver and used for receiving and transmitting a first RF signal and a second RF signal; a second module, electrically connected to the first module, used as the IF IQ modulator/demodulator of the dual-band RF transceiver; a third module, electrically connected to the first and the second modules, used as the tripe-band phase-locked frequency synthesizer of the dual-band RF transceiver and used for providing a first local oscillating signal and a second local oscillating signal to the first module, and a third local oscillating signal to the second module. The dual-band RF transceiver according to the present invention realizes the dual-band triple-mode operation of IEEE802.11 a/b/g by a single dual-band RF module, and therefore the circuit size, power dissipation, component count, and cost can be dramatically reduced.
