Products and Services

Cryoclock Pty Ltd develops state-of-the-art low noise and high stability oscillators for use in electronic systems that need the very best signals. We manufacture master oscillators with fractional frequency stabilities better than 1 part in 10    , world-class radio-frequency and microwave synthesizers that can translate the master oscillator signal to frequencies of interest with maximal fidelity, as well as low-noise radio-frequency and microwave signal distribution solutions over optical fibre.

cryoSapphire

Based on a whispering gallery mode of a cryogenically cooled sapphire crystal, Cryoclock’s cryoSapphire is an ultra-low phase-noise frequency oscillator that produces extremely stable signals from HF to X-band.
