Abstract :
Frequency converting systems can be severely limited by undesired spurious signals arising from combinations of odd and even harmonics of RF and LO inputs in an RF mixer. This work demonstrates the advantage of using photonic-assisted frequency conversion to reduce the impact of mixing spurs-both analytically and experimentally-showing truly 3rd-order limited performance and extending to millimeter wave frequencies.
