Established in 1994, RFX has evolved as a significant UK manufacturer of high frequency precision oscillators using AT cut, SC cut and IT cut quartz crystals.

From a modern high quality manufacturing facility based in Livingston, Scotland, the company produces innovative OCXO, TCXO, VCXO and PLL designs from 1MHz to 2.4GHz.

The RFX precision OCXO designs are amongst the smallest in the world with efficient use of power during warm up and operation. New smd versions and increasingly stringent specifications will evolve from an ongoing research and development programme to meet the demands of the telecommunications industry.
