Product Description
This Low Noise Space OCXO is designed for Clocks, Navigation and Positioning Systems. It
is used in such applications as GPS receivers, digital cards, onboard calculators, down and
up converters, synthesizers.
This frequency source is featured by remarkable frequency stability vs. temperature range
down to ±20 ppb under vacuum and a noise floor down to -165dBc/Hz.
The RK408 is manufactured in accordance with MIL-PRF-55310 (Class 1, type 4, level S), is available in different
packages in a volume of 40x50x20mm.
