A radio frequency (RF) receiver and receiving method are provided which can remove a leakage component from a received signal by using a local signal. In the RF receiver, a noise removing unit controls a gain and a phase of a local signal LOI according to a phase THETA and a gain AMPTD detected in a MODEM, estimates a signal V.sub.cal corresponding to a noise component introduced into a received RF signal RXIN, and removes the estimated signal V.sub.cal from the received RF signal RXIN. In this manner, a clean RF signal RXO, which does not include a noise component, is frequency-down converted in a receiving unit.
