Ultra Low Noise S-Band DRO for 2.856GHz

Developed for extremely jitter sensitive applications like electron beam accelerators, this voltage-controlled Dielectric-Resonator Oscillator delivers ultimate phase noise performance at 2.856GHz, comparable to quartz crystal oscillators.

With a high performance dielectric resonator at its heart, phase noise typically reaches ‑125dBc/Hz at 1kHz, ‑150dBc/Hz at 10kHz offset and –180dBc/Hz in the noise floor, yielding attosecond jitter performance when integrated from 10kHz to 30MHz.

Double buffering on the output keeps pulling below 1ppm (typically) and a two tier voltage stabilization scheme virtually eliminates pushing.

The tuning port accepts 0..10V for a ±60kHz tuning range and easy integration into phase-locked loops.

The DRO runs off a single +5,7V supply and provides high internal power supply noise rejection to facilitate integration in noisy environments.

Amplitude stabilization to ±0,1dB with output power setability to ±2dB is available as an option.


Available options:

HP:      Higher output power level of +17dBm.

ALC:    Amplitude stabilization to ±0.1dB with settable output amplitude to ±1dB via 0..+4V control input.
