VCXO | NEWSPACE LOW NOISE & LOW POWER SERIES Issue: A0, xxx.110, 12 November 2021 Specifications are subject to change without notice Copyright © 2021 Rakon Limited. All rights reserved Page 1 of 3 sales@rakon.com RK200NS [PRELIMINARY] The RK200NS is a cost-effective, low power consumption Space VCXO designed for NewSpace mini satellites and constellations. This VCXO is ideal for smallsats where tolerance to Total Ionizing Dose (TID), low power consumption, and good phase noise are required . It is designed for missions up to 12 years. The standard frequencies of the RK200NS are 10 MHz and 100 MHz. Custom frequencies are available from 10 to 120 MHz. The RK200NS is a small form-factor, low profile NewSpace VCXO in a 25 x 25 x 13 mm Pin Through Hole (PTH) package. Environmental Conditions Parameter Condition / Remarks Min. Typ. Max.
