HIGH RELIABILITY 10-7 STABILITY CLASS OCXO | SPACE SOLUTIONS Issue: 51001922.110, Issue A2. 05 January 2023 Specifications are subject to change without notice Copyright © 2018 to 2023, Rakon Limited. All right reserved Page 1 of 2 sales@rakon.com RK407 The RK407 is a Hi-Rel Space OCXO in the 10-7 frequency stability class. It is designed for scenarios where low power consumption is required, but where the frequency stability of a Space TCXO is insufficient. The RK407 delivers low phase noise in a compact flat pack package. Screening to MIL-PRF-55310 (Class 1, type 4, level S) guidelines or to an optimised and shorter flow are available for this product. The RK407 is ideal for communication equipment such as signal generation, transponders, digital cards, down and up converters and synthesizers. This Space OCXO is available with short lead-times.
