Classification: CPC H | IPC H

Claim 15:
16. A system comprising a transmitter (TX) and a measurement receiver (MRX), the system comprising:
a first local oscillator (LO) generator comprising a first frequency doubler and a first frequency divider, the first frequency doubler being configured to receive a voltage controlled oscillator (VCO) signal having a first frequency and generate a first signal fed into the first frequency divider, the first signal having a second frequency that is twice the first frequency, wherein the first frequency divider is configured to generate a plurality of TX LO signals;
a second LO generator comprising a second frequency doubler and a second frequency divider, the second frequency doubler being configured to receive the VCO signal and generate a second signal fed into the second frequency divider, the second signal having the second frequency, wherein the second frequency divider is configured to generate a plurality of MRX LO signals;
the TX configured to convert digital in-phase and quadrature-phase signals to a plurality of phase signals, and generate an analog TX output signal based on the plurality of phase signals and the plurality of TX LO signals; and
the MRX configured to receive the analog TX output signal and generate measurement signals including distortion signals.
