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 four types: Single Loop PLDRO, Dual Loop PLDRO, Fractional-N PLDRO, and Variable Frequency PLDRO.

The variable frequency PLDRO series is an innovative 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.
