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, Fractonal-N 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.
