ing on zero IF. SAW filter guarantees 14dBc attenuation at alternating channels, which
gives acceptable receiver IMD performance with only moderate VHF local phase noise
performance. The local signal's partition to receiver selectivity and IMD depends then
mainly on the spectral purity of the 1st local. Zero 2nd IF stages include most of receiv-
ers signal gain, AGC control range and channel filtering.
