Patent ID: 7680477

Claim:
A circuit comprising: an amplifier coupled to a signal input, the amplifier to amplify a signal provided by the signal input to a specified level, the amplifier comprising a first tunable capacitor, wherein the first tunable capacitor is tuned by a reference oscillator, and wherein the first tunable capacitor is configured to tune a matching network coupled to the signal input to meet specified return loss requirements; a tunable inductor-capacitor (LC) filter having an input coupled to an output of the amplifier and an output coupled to a mixer, the tunable LC filter comprising: an input stage comprising: a first pair of inductors arranged in a dipole configuration, each inductor created from a high Q conductive material; a second tunable capacitor coupled in parallel to the first pair of inductors, the second tunable capacitor to adjust the frequency response of the input stage; and an output stage inductively coupled to the input stage, the output stage comprising: a second pair of inductors arranged in a dipole configuration, each inductor created from a high Q conductive material; and a third tunable capacitor coupled in parallel to the second pair of inductors, the third tunable capacitor to adjust the frequency response of the output stage.
