The PLDRO (Phase Locked Dielectric Resonator Oscillator) provides the ultra-low phase noise and excellent frequency stability when it is phase locked to a clean and stable crystal reference signal.

Our PLDRO series are available in three types: Single Loop PLDRO, Single Loop Digital-PLDRO and Dual Loop PLDRO.

The Dual Loop PLDROs provide an output frequencies whose phase is locked to an integer or fractional multiple of the external reference using PLCRO (Phase Locked Coaxial Resonator Oscillator) and frequency divider. This series provide output frequency from 5 GHz to 13 GHz with 500 KHz frequency resolution. For more finer frequency resolution, please refer to Single Loop Digital-PLDRO.
