Abstract
A receiver apparatus coupled to receive an RF signal having frequency components in a desired band and an image band, includes: an image rejection filter; a local oscillator to produce a first signal; a frequency divider to produce a plurality of second signals; a first mixer, coupled to receive the RF signal and the first signal, to produce an intermediate signal; and a frequency translation filter including a plurality of mixers each coupled to receive the intermediate signal and a different one of the plurality of second signals; and at least one impedance coupled as a load to each of the plurality of mixers, wherein: the image rejection filter and the frequency translation filter are configured to operate in conjunction to form a band-pass filter in the desired band and a band-stop filter in the image band and to apply the band-pass filter and band-stop filter to the RF signal.
