Description

Microwave Dynamics’ Ovenized Crystal Oscillators provide high stability (0.1 ppm) in the frequency range of 70 to 120 MHz. Built to the same high standards as our Dielectric Resonator Oscillators, these OCXOs provide an excellent reference input complementing our DRO line. OCXOs  feature high stability, fast warm-up, low power requirements, rugged military type housings and fast delivery.
