ABSTRACT:
An apparatus and method for generating an intermediate frequency (IF) to be transferred to a single sideband (SSB) generator which generates carriers using one local oscillator (LO) signal and at least two IF signals that are received. A group signal is generated which includes a non-phase-shifted signal and a phase-shifted signal to a predetermined value with respect to each IF. One of the group signals is selected and transferred to the SSB generator. Accordingly, the SSB generator performs the phase shift on the LO signal alone.
