Abstract
Highly precise signal generation technique is a key for the realization of low-noise radar and ghost-less imaging in millimeter-wave bands. Current technologies based on an oven-controlled oscillator has a better phase noise characteristic; however, relatively low frequency requires multiplication technique to upconvert the signal into millimeter-wave range. In the study, we configured an optoelectronic oscillator (OEO) employed with an optical frequency comb generation using an optical modulator. An optical filter bank implemented in the OEO loop performs an optical path optimization to realize 95-GHz millimeter-wave signal with a phase noise of -86 dBc/Hz at an offset frequency of 10 kHz.
