Low SWaP-C Mini-Rubidium Oscillator

The Spectratime mRO-50 is a breakthrough low SWaP-C Miniaturized Rubidium Oscillator designed to meet the latest commercial, military and aerospace requirements where time stability and power consumption are critical.

It provides a one day holdover below 1µs and a retrace below 1 x 10-10 in a form factor (50.8 x 50.8 x 19.5mm) that takes up only 51 cc of volume (about one-third of the volume compared to standard rubidiums) and consumes only 0.45W of power, which is about ten times less than existing solutions with similar capabilities.
