HIGH RELIABILITY 10-8 STABILITY CLASS OCXO | SPACE SOLUTIONS Issue: A6, 51001203.110, 18 July 2024 Specifications are subject to change without notice Copyright © 2012 to 2024, Rakon Limited. All rights reserved Page 1 of 5 Contact Us RK408 The RK408 is a high-reliability Space OCXO in the 10-8 frequency stability class. This OCXO series is meticulously engineered to generate ultra-low phase noise signals across frequencies from 10 to 125 MHz. The RK408 provides exceptional stability even in extreme temperature variations, with deviations as low as ±20 ppb in a vacuum environment. Additionally, it exhibits an extremely low noise floor, reaching levels of -165 dBc/Hz at a high frequency of 120 MHz. The RK408 Space OCXO has two package types: SM1 (Micro D + SMA) and PS1 (Pin side + SMA), providing flexibility to meet system board requirements. For this product, Rakon can perform thorough testing following MIL-PRF-55310 (Class 1, type 4, level S) or provide a streamlined and optimised screening process tailored to specific needs. The RK408 satisfies high precision and reliability demands in navigation, positioning, and SAR (Synthetic Aperture Radar) systems.
