RK409NS | NEWSPACE ULTRA STABLE OSCILLATOR SERIES Issue: A3, 51002753.110. 8 April 2024 Specifications are subject to change without notice Copyright © 2020 to 2024, Rakon Limited. All right reserved Page 1 of 5 Contact Us RK409NS The RK409NS is a NewSpace OCXO with a frequency stability of 10-9. This cost effective and low phase noise OCXO is designed specifically for the NewSpace market, such as mini -satellites and constellations. The NewSpace OCXO is an ideal choice for applications demanding high tolerance to Total lonizing Dose (TID) and excellent phase noise performance, with a mission life of up to 12 years. The standard frequency of the RK409NS is 10 MHz, with additional frequencies ranging from 10 to 40 MHz available upon request.
