Abstract
A low IF receiver for operation at an intermediate frequency (IF), comprises an antenna port configured to receive a receive signal comprising a wanted RF signal at an RF frequency and a blocker RF signal at a mirror image frequency of the wanted RF signal with respect to a frequency of an local oscillator (LO) signal, from an antenna. Further, the low IF receiver comprises a first mixer component configured to down convert the wanted RF signal and the blocker RF signal to an intermediate frequency (IF) signal, based on the frequency of the LO signal, wherein the IF signal comprises a wanted IF signal at a first intermediate frequency and a blocker IF signal at a second intermediate frequency and a second mixer component configured to receive the IF signal, separate the IF signal into the wanted IF signal and the blocker IF signal, and provide the wanted IF signal at a first output thereof and the blocker IF signal at a second output thereof, based on a tuning signal. In addition, the low IF receiver comprises a power estimation component configured to receive the blocker IF signal, measure a power of the blocker IF signal and select the frequency of the LO signal to be applied to the first mixer component from a plurality of LO frequencies, based on the measured power of the blocker IF signal.
