Claim Text:
1. A method for rapidly generating a signal at an output frequency for use in a communication device comprising: providing a reference signal at a reference frequency to a first signal synthesizer configured to generate a first signal at a first frequency; generating the first signal with the first signal synthesizer; providing the reference signal at the reference frequency to a second signal synthesizer configured to generate a second signal at a second frequency; generating the second signal with the second signal synthesizer; providing the first signal and the second signal to a switch; responsive to a control signal, selectively outputting either the first signal or the second signal from the switch as part of a switching operation; responsive to switching operation, applying a first frequency modification to the first signal or a second frequency modification to the second signal to thereby generate a frequency specific signal at an output frequency; and outputting the frequency specific signal without the frequency specific signal passing through any switches after the frequency modification, such that the switching operation is the only switching operation when producing the frequency specific signal.
