ABSTRACT:
Aspects of a method and system for a distributed transceiver with DDFS channel selection may include frequency-translating a first signal to generate one or more second signals utilizing a distributed mixer and an in-phase and quadrature mixing stage. The first signal may be an input signal to the distributed mixer, which may comprise a plurality of frequency conversion stages. The input signal to the distributed mixer may be an input signal to at least one of the plurality of frequency conversion stages and an output signal of the distributed mixer may be generated from one or more output signals or the plurality of conversion stages. The output signal from the distributed mixer may be an input signal to the in-phase and quadrature mixing stage and the one or more second signals may be generated from one or more output signals of the in-phase and quadrature mixing stage.
