Patent ID: 8649753

Claim:
A method for processing communication signals, the method comprising: generating a second signal from a first signal by: frequency-translating said first signal by switching a first current associated with said first signal between a first signal path and a second signal path; filtering said switched first current via a microstrip filter or a coplanar waveguide filter tuned to a desired frequency component of said frequency-translated first signal, wherein said microstrip filter or said coplanar waveguide filter is programmable by dynamically adjusting an inductance of one or more inductors physically connecting a plurality of resonator sections to one another within said microstrip filter or said coplanar waveguide filter, wherein said microstrip filter or said coplanar waveguide filter is coupled to said first signal path and said second signal path; applying a DC bias voltage to said microstrip filter or said coplanar waveguide filter; and generating said second signal from the difference between the voltage of said first signal path and said second signal path.
