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 PLDRO series are available in four series products: Single Loop PLDRO, Dual Loop PLDRO, Fractional-N PLDRO, and Variable Frequency PLDRO. The Fractional-N PLDRO is an innovative phase locked dielectric resonator oscillator that solves the reference frequency dependence of the output frequency. This PLDRO series can generate any frequency in 1 KHz steps within 5 GHz to 28 GHz and has the same phase noise performance as Single Loop PLDRO.
