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. The PLDRO provides ideal signal for commercial and military systems requiring ultra-low phase noise, low spurious, and high frequency stability.
Our PLDRO series are available in three types: Single Loop PLDRO, Single Loop Digital-PLDRO, and Dual Loop PLDRO.

●  Single Loop PLDRO
The Single Loop PLDROs provide an output frequencies whose phase is locked to an integer multiple of the external reference. This series provide output frequency up to 28 GHz. In addition, two package options are available. The first option corresponds to single bed package without Frequency Multiplier. This option provides output frequency from 5 GHz to 13 GHz and is the slimmest package in our PLDRO products. The second option corresponds to double bed package with Frequency Multiplier. This option provides an output frequency from 14 GHz to 28 GHz and has a double bed hosing construction.

●  Single Loop Digital-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.

●  Dual Loop PLDRO
The Dual Loop PLDROs provide an output frequencies whose phase is locked to an integer or fractional multiple of the external reference using PLCRO (Phase Locked Coaxial Resonator Oscillator) and frequency divider. This series provide output frequency from 5 GHz to 13 GHz with 500 KHz frequency resolution. For more finer frequency resolution, please refer to Single Loop Digital-PLDRO.
