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, Fractional-N PLDRO, and Dual Loop 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.
