摘要： A system and method for generating an LO signal for an RF transmitter is provided that eliminates the risk of LO-pulling. A filtering technique is employed to select the desired harmonic of a VCO signal, usually the third. The required in-phase and quadrature LO signals can be derived by means of dividers. Any harmonic relation is avoided between the transmit signal and the VCO frequency, without generation of intermediate signals close to the VCO frequency, thus circumventing pulling of the VCO.
