ABSTRACT:
A local oscillation signal generator and a multi-band transceiver including the local oscillation signal generator are provided. The multi-band transceiver includes a fractional-N phased locked loop (PLL), a local oscillation signal generator, and a transmitter. The fractional-N PLL receives a reference signal and outputs an oscillation signal that is phase-locked to the reference signal. The local oscillation signal generator receives the oscillation signal and outputs a first divided signal that is obtained by dividing a frequency of the oscillation signal by a first value and a second divided signal that is obtained by dividing the frequency of the oscillation signal by a second value. The transmitter receives input signals and generates a transmitter signal using an equationfTX=(23⁢k-1M)⁢fVCO,based on the first divided signal and the second divided signal.
