Claim 20:
21. A method for calibration of a transceiver (TRX) comprising a transmitter (TX) and a measurement receiver (MRX), the method comprising:
receiving a first signal generated by a voltage controlled oscillator (VCO) having a first frequency;
in a first mode of operation:
producing a first TX signal having a second frequency that is a double of the first frequency;
producing a second TX signal having a third frequency that is one third of the second frequency;
producing a first MX signal having the second frequency;
producing a second MX signal having the third frequency; and
transmitting outgoing RF signals using the second TX signal having the third frequency; and

in a second mode of operation:
producing a third MX signal having a fourth frequency that is one half of the third frequency;
transmitting outgoing RF signals using the second TX signal having the third frequency; and
processing MRX signals in the MRX receiver using the third MX signal having the fourth frequency.
