Product Description
The RK407 is a Space OCXO dedicated to Telecom payloads as it is in the 10^-7 stability class
over the temperature range with an overall frequency drift less than 2ppm over 18 years
and available with a short lead time.
It is designed for clocks, signal generation applications, transponders, GPS receivers, digital
cards, board calculators, down and up converters, and synthesizers.
This frequency source is a good trade-off between overall frequency stability and power consumption. It is
manufactured in accordance with MIL-PRF-55310 (Class 1, type 4, level S) and is available in a flat pack package
(25x25x17mm).
