Patent ID: 8467757

Claim:
A wideband receiver for a wireless communication system, the wideband receiver comprising: a receive path having a mixer for receiving a Radio Frequency (RF) signal having a frequency f SG and for converting the RF signal into an Intermediate Frequency (IF) signal having a frequency f IF by mixing the RF signal with a first local oscillation signal having a first local oscillation frequency f LO1 , and at least one Phase Locked Loop (PLL) for providing the first local oscillation signal to the mixer; and a control block for determining whether a half-IF signal having a center frequency of f SG −f IF /2 exists in the IF signal, and when the half-IF signal exists, for controlling the at least one PLL to generate a second local oscillation signal having a second local oscillation frequency f LO2 greater than the first local oscillation frequency f LO1 .
