RK406NS | LOW NOISE & LOW POWER OSCILLATOR SERIES Issue: A5, 51002641.110, 22 April 2024 Specifications are subject to change without notice Copyright © 2020 to 2024, Rakon Limited. All rights reserved Page 1 of 6 Contact Us RK406NS The RK406NS is a cost-effective, low power consumption OCXO developed for NewSpace applications, including mini-satellites and satellite constellations. With its compact footprint of 25.4 x 25.4 mm, this NewSpace OCXO is ideal for missions of up to 5 years where tolerance to TID (Total Ionizing Dose), low power consumption, and excellent phase noise are required. The product can be customised for a longer lifetime of up to 12 years. The standard frequencies of the RK406NS are 10, 10.23, 10.24, 40 and 100 MHz. Frequencies ranging from 10 to 125 MHz can be developed on request. Environmental Conditions Parameter Condition / Remarks Min. Typ. Max.
