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.
Our PLDRO series are available in three types: Single Loop PLDRO, Single Loop Digital-PLDRO and Dual Loop PLDRO.

The Single Loop Digital-PLDRO can provide any output frequency in 5 GHz to 13 GHz. This series generates output frequency by shifting the phase of the output frequency using a Frequency Divider, DDS and Mixer so that the output frequency is an integer multiple of the reference frequency. This series also offers very fine frequency resolution of 10 KHz.
