The OX-205 is an Ultra Low Phase Noise Ovenized Crystal Oscillator with a noise floor as low as -176 dBc/Hz in a compact 1” x 1”
enclosure. Designed for applications that demand extremely low noise sources, including the reference oscillator for a phase-locked
loop in the microwave spectrum. Custom frequencies available upon request.
