OCXO and OCSO Overview

Rakon has extensive experience in creating standard and customised Oven Controlled Crystal Oscillator (OCXO) solutions for the Telecommunications, Space and Defense markets. Rakon's Oven Controlled SAW Oscillators (OCSOs) feature remarkable performances in terms of frequency stability, ageing and g-sensitivity. They feature low noise floor performance without degrading close-in phase noise. OCSOs are favoured when ultra low phase noise performance is required, especially in conjunction with high frequencies.

High Reliability Space OCXO

►  PROFILE: The high reliability Space OCXO series is manufactured in accordance with MIL-PRF-55310 and is ITAR-free. They are designed for space applications. The key advantages of this range of OCXO are their remarkable overall frequency stability vs. temperature range up to ± 0.5 ppb under vacuum, for the mini Ultra Stable Oscillators (USO).

APPLICATIONS:  Transponders, GPS receivers, Digital cards, Down and up converters, Onboard calculators, Synthesizers, Frequency Generation Units (FGU), Navigation and Positioning systems, Gyroscopes and Master clocks.
