Methods and systems for a local oscillator generator based on quadrature mixing using a phase shifter. Aspects of one method may include generating a local oscillator signal, where a frequency of the local oscillator signal may be determined by controlling a phase of in-phase (I) components and quadrature phase (Q) components of a first signal and a second signal. For example, by appropriately controlling a phase of each component that is to be mixed, the local oscillator signal may have a frequency that is the sum of a frequency of the first signal and a frequency of the second signal, or a difference of the frequency of the first signal and the frequency of the second signal.
