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 four types: Single Loop PLDRO, Dual Loop PLDRO, Fractional-N PLDRO, and Variable Frequency PLDRO.

The Single Loop PLDRO is a phase locked dielectric resonator oscillator whose output frequency is generated by a single phase locked loop. Our Single Loop PLDRO series consists of various types of housings.
