Abstract
Disclosed is a frequency scouting circuit with an adjustable frequency synthesizer. The scouting circuit may be collocated with other radio frequency integrated circuits on the same die. The synthesizer may include a dedicated oscillator, and the synthesizer may be adapted to generate a mixing signal at a given frequency. A channel monitoring circuit block may be adapted to determine availability of a carrier frequency corresponding to the mixing signal frequency, and control logic may be adapted to select the given frequency from a set of possible transmission carrier frequencies for a functionally associated transmitter.
