An intermediate transmit mixer (34) generates an intermediate transmit signal by mixing a transmit modulated signal with a harmonic (45) of the intermediate transmit oscillator signal. Furthermore, the transceiver has a final transmit mixer (40) to generate an output transmit signal by mixing the intermediate transmit signal with a harmonic (41) of the transceiver drive signal. A transceiver drive mixer generates an intermediate phase detect signal by mixing the transceiver drive signal with a harmonic of the intermediate transmit oscillator signal. The intermediate phase detect signal is phase locked with the stable low frequency reference signal.
