Poseidon Scientific Instruments, world leaders in ultra low phase noise signal generation and measurement since 1993.

Poseidon Scientific has led sapphire oscillator technology since the release of the SLC series of high-Q sapphire whispering gallery mode resonators. For over 20 years we have been committed to growing our intellectual property through a demanding research and development regime. This commitment has given us deep expertise in the lowest phase noise; what causes it and how to minimise it.

The Poseidon Scientific Instruments sapphire oscillators continue to be the lowest phase noise microwave signal generators in the world. For ten years our SBO oscillator range has been the highest performing, lowest noise signal generator for mobile platforms. Our R&D program and know-how has developed dielectric resonator oscillators (DRO) for radar, telecommunications (SONET & SDH) radio astronomy and particle accelerator applications.

Poseidon's Founder and Managing Director Jesse Searls was the recipient of the CB Sawyer Memorial Award, an international accolade given by the Institute of Electrical and Electronic Engineers (IEEE) for the 'for the development and successful commercialization of microwave signal sources exhibiting spectral purity that significantly advances the state-of-the-art'.
