Product Description
This stable oscillator is designed for Space Clocks, Navigation and Positioning Systems and is
used in such applications as GPS receivers, digital cards, board calculators, down and up
converters, synthesizers.
The AV (Allan Variance) variant of the RK409 has a short term stability of 6.10^-13 at 1 s.
This frequency source is featured by remarkable overall frequency stability vs. temperature
range up to ± 0.5 ppb under vacuum and ± 20 ppb per year.
The RK409 is available with different packages, in a small format (50x50x30mm) and is
manufactured in accordance with MIL-PRF-55310 (Class 1, type 4 or type 6, level S or B).
