Adjacent channel optimized receiver

1. A method comprising:

receiving a radio signal, wherein the radio signal comprises at least a carrier frequency;

converting the radio signal to an intermediate frequency signal, said intermediate frequency signal different from the carrier frequency;

filtering the intermediate frequency signal through a first channel select filter, said first channel select filter being one of a plurality of programmable channel select filters;

determining if an interfering signal is present;

selecting a second channel select filter in response to said determining;

altering the intermediate frequency in response to said determining, and

directing the intermediate frequency signal to the second channel select filter,

wherein said determining is effectuated using a radio receiver operable to provide a control signal to the plurality of programmable channel select filters.

2. The method of claim 1 said altering the intermediate frequency is effectuated with a second control signal coupled from the receiver to a programmable local oscillator.

3. The method of claim 1 further including:

filtering the radio signal before converting the radio signal to the intermediate frequency signal.

4. The method of claim 1 wherein the plurality of programmable channel select filters are controlled by switches operable to direct the intermediate frequency to one of the plurality of programmable channel select filters.

5. The method of claim 1 wherein either the first or the second channel select filter is a surface acoustic wave (SAW) filter.

6. The method of claim 1 further including:

up-converting the intermediate frequency signal, and

coupling the up-converted signal to the receiver.

7. The method of claim 6 further including:

filtering the up-converted signal through a first band select filter, said first band select filter being one of a plurality of programmable band select filters.

8. The method of claim 7 further including:

altering the first band select filter in response to a third control signal, said third control signal coupled from the receiver to the plurality of programmable band select filters.

9. The method of claim 6 wherein said up-converting is effectuated with a second control signal coupled from the receiver to a programmable local oscillator.

10. A method comprising:

receiving at a radio receiver a radio signal, said signal substantially in a first frequency band;

determining the presence of an interfering signal;

providing, from the radio receiver, a band select control signal, a channel select control signal and an oscillator control signal;

directing the oscillator control signal to a programmable oscillator;

directing the band select control signal to band select filters;

directing the channel select control signal to switches,

wherein the band select control signal, the channel select control signal and the oscillator control signal are controlled by the radio receiver to minimize interference from the interfering signal.

11. The method of claim 10 wherein the oscillator control signal controls a programmable oscillator that is coupled to a plurality of mixers that alter an intermediate frequency signal to minimize the interference.

12. The method of claim 11 wherein the switches are operable to direct the intermediate frequency signal to one of a plurality of channel select filters.

13. The method of claim 12 wherein the channel select filters are surface acoustic wave filters.

14. The method of claim 10 further including:

converting the radio signal to an intermediate frequency signal before it is received at the radio receiver.

15. The method of claim 10 further including:

filtering the radio signal before converting the radio signal to an intermediate frequency signal.

16. The method of claim 15 wherein the intermediate frequency signal is shifted to minimized interference.

17. A device that performs the method of claim 10 .
