Patent ID: 8179167

Claim:
A frequency synthesizer comprising: a multiplexer coupled to receive a plurality of sinusoidal signals, each sinusoidal signal having a unique, frequency; and a band group selector to selects between a plurality of band groups, the band group selector coupled to receive a first signal from the multiplexer, wherein the multiplexer multiplexes between the plurality of sinusoidal signals and provides the first signal, wherein the band group selector includes a band mixer, the band mixer mixes the first signal with a sinusoidal band signal having a band frequency, the band signal corresponding to a band group selected from the plurality of band groups, the band mixer providing a second signal, wherein the band group selector provides a transmitter mixer signal and a receiver mixer signal corresponding to the second signal, wherein the unique frequency corresponds to a first multiple of a base frequency, wherein the band frequency corresponds to a second multiple of the base frequency, wherein the second multiple is greater than the first multiple.
