Patent ID: 8670739

Claim:
A frequency translated filter, comprising: a plurality of transconductance cells configured to convert a received radio frequency (RF) voltage signal into a respective plurality of RF current signals, wherein each of the plurality of transconductance cells provides an effective transconductance of a first magnitude for frequency components of the received RF voltage signal arising from a first harmonic and an effective transconductance of a second magnitude less than the first magnitude for frequency components of the received RF voltage signal arising from harmonics at integer multiples of the first harmonic; a plurality of frequency conversion cells coupled to the plurality of transconductance cells and configured to mix respective ones of the plurality of RF current signals with a plurality of non-overlapping local oscillator (LO) signals; and a plurality of baseband impedances coupled between outputs of the plurality of frequency conversion cells and ground, wherein the plurality of baseband impedances are frequency translated by mixed signals from the plurality of frequency conversion cells.
