MUTI-MODE LOCAL OSCILLATOR AAND METHOD FOR OSCILLATING

摘要

PURPOSE: A multi-model local oscillator and a method for oscillating the same are provided to generate local oscillating signal using demultiply signal which has a lower frequency than that of oscillating signal. CONSTITUTION: A demultiplying unit(120) outputs a plurality of demultiply signals by demultiplying a pre-set frequency band of oscillating signal which is output from a voltage control oscillator. A signal selection unit(130) selects one of the demultiply signals in response with selection control signal. A mixer(140) mixes the selected signal and one of the demultiplying signals and outputs local oscillating signal.
