摘要
Aspects of a method and system for a high-precision frequency generator using a direct digital frequency synthesizer for transmitters and receivers may include generating a second signal from a first signal by frequency translating an inphase component of the first signal utilizing a high-precision oscillating signal that may be generated using at least a direct digital frequency synthesizer (DDFS) and at least a Phase-Locked Loop (PLL). A corresponding quadrature component of the first signal may be frequency translated utilizing a phase-shifted version of the high-precision oscillating signal. The inphase component of the first signal may be multiplied with the high-precision oscillating signal and the quadrature component of the first signal may be multiplied with the phase-shifted version of the high-precision oscillating signal. The second signal may be generated from the first signal by adding the frequency translated inphase component to the frequency translated quadrature component.
