Abstract
A fast mode switching frequency synthesizing apparatus and method for operating in low power consumption. In the frequency synthesizer, according to a mode control signal, an SSB mixer selectively generates and outputs a signal having a frequency which is identical to an input signal RF or outputs a signal having a frequency which is a synthesized frequency of the input signals RF and LO. Frequency synthesized signals having a frequency which is a sum of frequencies of the input signals RF and LO, or a difference of frequencies therebetween, may be generated by changing wiring of a path switch according to a phase control signal.
