Description

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. The PLDRO provides ideal signal for commercial and military systems requiring ultra-low phase noise, low spurious, and high frequency stability.
Our PLDRO series are available in three types: Single Loop PLDRO, Fractional-N PLDRO, and Dual Loop PLDRO.

●  Single Loop 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 is available in four types of housings.

●  Fractional-N PLDRO
The Fractional-N PLDRO is an innovative phase locked dielectric resonator oscillator that improves the reference frequency dependence of the output frequency. This PLDRO series can generate any frequency in 10KHz steps within 5 GHz to 13 GHz, has the same phase noise characteristics as Single Loop PLDRO, and cheaper than Dual Loop PLDRO. In addition, this PLDRO series has the same housing size and lower power consumption compared to Dual Loop PLDRO.

●  Dual Loop PLDRO
The Dual Loop PLDRO is a phase locked dielectric resonator oscillator whose output frequency is generated by a dual phase locked loop. This PLDRO series provides 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.
