Abstract :
A novel approach to the design of optically synchronized millimeter-wave local oscillators is introduced based on the subharmonically injection-locked phase-lock loop technique. Two oscillators at 18 GHz were designed and constructed to demonstrate the validity of this approach. The experimental results support the desired goal of frequency and phase coherence of the millimeter wave oscillators while maintaining the low FM noise degradation and large subharmonic locking range.<>
