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: Single Loop PLDRO, Dual Loop PLDRO, Fractional-N PLDRO, and Variable Frequency PLDRO. The variable frequency PLDRO series is a signal generator capable of providing both the ultra low phase noise performance of the PLDRO and the excellent frequency resolution of a direct digital synthesizer. This PLDRO series covers 5 GHz to 29 GHz and output frequency can be varied in steps of 10 KHz or less within a specified bandwidth.
