High Reliability TCXO | Space Solutions Issue: B, 2 August 2024 Specifications are subject to change without notice. Copyright © 2021 to 2024 Rakon Limited. All rights reserved Page 1 of 3 Contact Us RTX3520S The RTX3520S is a radiation-tolerant TCXO in a 35 x 20 mm hermetically sealed package. This TCXO is specifically designed to meet high-frequency performance requirements. It is ideal for applications where high power, harmonics, excellent phase noise, and accurate frequency stability over a wide temperature range are crucial. With a standard model height of 15 mm, a low-profile 10 mm package option is available to suit limited height working environments. Environmental Conditions Parameter Test Conditions/Description Min.
