Abstract:
1. A device comprising: a down-converter operative to receive a first RF signal and generate a second RF signal; one or more channel select switches coupled to a plurality of filters, said switches operative to direct the second RF signal to at least one of said filters; a programmable oscillator, said oscillator coupled to the down converter; a receiver coupled to the oscillator, said receiver operable to provide a control signal to the oscillator, said control signal indicative of an interference signal substantially near the skirts of one of said filters; wherein the control signal operates to change the oscillator frequency, having the effect that the frequency of the second RF signal is shifted; wherein the control signal is further operable to select for a filter having a center frequency different from the center frequency of the second RF signal, and an up-converter, coupled to the channel select switches and operative to generate a third RF signal.
