Product Description
OCXO Space Flat Pack is designed for space 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 of 0,5W.
OCXOs Space Flat Pack (25x25x17mm) are manufactured in accordance with
MIL-PRF-55310 (Class 1, type 4, level S).
