LOCAL OSCILLATOR FOR A DIRECT CONVERSION TRANSCEIVER

摘要

A local oscillator circuit for generating a local frequency signal is provided. The local oscillator circuit may cooperate with a radio circuit for providing wireless reception or transmission. The radio circuit performs modulation or demodulation processes with reference to a defined carrier signal frequency. The local oscillator circuit has a voltage controlled oscillator that generates a VCO signal at frequency different than the carrier frequency. A frequency scaling circuit applies a scaling factor to the VCO signal, with the scaled signal generated at the frequency of the defined carrier frequency.
