High Reliability Space OCXO

The high reliability Space OCXO series is designed and manufactured following MIL standards.  Designed for space applications, the key advantages of these OCXOs are their remarkable overall frequency stability vs. temperature range, which can offer stabilities as low as ±0.5 ppb under vacuum, as well as their long-term stabilities. The SWaP-optimised mini Ultra Stable Oscillators (USO) add to this a small form factor and low power consumption. The RK4 series is free from export regulations (ITAR free).

Applications: transponders, GNSS receivers, digital cards, down and up converters, onboard calculators, synthesizers, Frequency Generation Units (FGUs), navigation and positioning systems, gyroscopes and master clocks.

Country of origin: France (RK4 series), India (ROX-S series)
