Ultra Low Noise C-Band DRO for 7.225 GHz

Developed for extremely jitter sensitive applications, this voltage-controlled Dielectric-Resonator Oscillator delivers ultimate phase noise performance at 7.225GHz, comparable to quartz crystal oscillators.

With a high performance dielectric resonator at its heart, phase noise typically reaches ‑115dBc/Hz at 1kHz, ‑145dBc/Hz at 10kHz offset and <–175dBc/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) while delivering a high output power of +19 dBm. And a two tier voltage stabilization scheme virtually eliminates pushing.

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

Available options:

TP:      Tuning Port with ±100 kHz Tuning Range (0 .. +10V)
