Abstract
A multi-input multi-frequency synthesizing apparatus and method for a multi-band radio frequency (RF) receiver. The frequency synthesizing apparatus may generate an output from a greater number of high frequency signals by using one multi-input single side band (SSB) mixer. The multi-input SSB mixer may generate a signal whose frequency is an addition of frequencies of two signals selected from a signal selection control unit, or a difference of frequencies therebetween. According to a circuit configuration of the multi-input SSB mixer, the signal selection control unit may select more than two signals.
