Abstract

Microwave photonic mixer owns the advantages of wide frequency coverage range and large processing bandwidth. However, the LO spurious of the mixer is still high, which severely limits its application where the LO spurious locate at the band of interest. In this paper, a novel microwave photonic mixer with complete suppression of LO spurious is proposed. A dual-drive mach-zehnder modulator (DD-MZM) is adopted. The LO signal and RF signal are applied to the DD-MZM through the two driven ports. The optical signal is controlled to make the LO signal to be the phase modulation and the IF signal to be the intensity modulated. Finally, after the intensity detection completed by the photodetector, only the IF signal will be preserved and the LO spurious can be all suppressed. A proof-of-concept experiment is performed. Experimental result shows that 50-dB suppression of LO spurious can be realized.
