Low aging, high precision SMD crystals for RF clock applications

ACT now offer RF clock reference crystals fully optimised for RF/wireless and all other demanding applications requiring tight frequency stability, tolerance and low aging.

Long term-stability

The various packages consist of high-quality SMD crystals in a ceramic base/metal lid, seam-sealed for long-term stability. The lid is grounded via the conductive seal to the spare pads on the base, which assists overall EMI reduction.

Fully optimised for demanding applications

The crystals are fully optimised for RF clock/wireless applications and meet the tight frequency control demands of Bluetooth®, Zigbee® and other WLan/ISM band low power radio applications.
