Description
The PLDRO (Phase Locked Dielectric Resonator Oscillator) provides the ultra-low phase noise and an excellent frequency stability when it is phase-locked to a clean and stable crystal reference signal. The PLDRO provides ideal signal for commercial and military systems that require ultra-low phase noise, low spurious, and high frequency stability.
Our PLDROs are available in four series products: 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. The Single Loop PLDRO series are classified into various types of PLDROs.
