Abstract
A millimeter-wave (mm-wave) harmonic signal generation method is proposed
and verified experimentally. The mm-wave harmonic signals of high order are
generated through the intrinsic nonlinear transfer characteristics of the
Mach–Zehnder amplitude modulator. A tunable single-resonance
microwave photonic filter is used to select the specific order of harmonic
signal. Signals up to the fourth harmonic at 20 GHz can be generated by
low-frequency driving signal at 5 GHz.
