Abstract
A transmitting apparatus operative at a plurality of different bands includes at least a modulator, an intermediate frequency (IF) filter, and an offset phase-locked-loop (OPLL). Regardless at which one of the frequency bands the transmitting apparatus operates, a divisor of at least one frequency divider included within the OPLL is fixed, and a signal, which is outputted by a controllable oscillator and received by an offset mixer included within the OPLL, corresponds to a substantially fixed frequency.
