Abstract
A receiver and method for identifying the frequency of an RF component in an RF signal are disclosed. The receiver includes a first mixer that receives an RF signal and mixes that RF signal with a first multi-tone LO signal that includes a plurality of tones to generate a mixed signal. The output of the first mixer is filtered by a first filter that removes signals outside of a predetermined band to generate a first IF signal. A processor determines the RF frequency of the component utilizing the first IF signal and a second IF signal generated using a second multi-tone LO signal having a different plurality of tones from said first multi-tone signal. The first and second multi-tone LO signals can be generated by clocking suitable digital sequences into the mixer either by using different sequences or by using the same sequence clocked at a different rate.
