Abstract
PURPOSE:After the addition of the oscillation frequency of a frequency variable oscilator and that of the 1st reference oscillator, the difference between the added result and the oscillation frequency of the 2nd reference oscillator is extracted, thereby preventing undesired components from existing around desired components generated at the output of a mixer.
