HIGH RELIABILITY 10-8 STABILITY CLASS OCXO | SPACE SOLUTIONS Date: 29 May 2018 Issue: Shortform, 51001203.110, Issue A4 Specifications subject to change without notice Page 1 of 2 www.rakon.com Specific requests can be emailed to Rakon: hirel@rakon.com RK408 MS1 The RK408 MS1 platform is a Space OCXO generating an ultra-low noise signal at low and high frequencies. This frequency source is featured by a remarkable frequency stability vs. temperature range down to ±20 ppb under vacuum and a noise floor down to -165 dBc/Hz. The RK408 MS1 can be screened following the guidance of MIL-PRF-55310 (Class 1, type 4, level S) or to an optimised and shorter flow. This product platform is ideal for navigation, positioning and SAR systems. Environmental Conditions Parameter Condition / Remarks Min. Typ. Max.
