CRYSTAL RESONATORS

Rakon manufactures Crystal resonators where high reliability, traceability and state of the art technology are required.
AT, SC, BT, IT, Y cuts are available in standard packages (HC-43, HC49, HC52, HC40, TO8/HC37, TO5/HC35).
They are sealed under vacuum or neutral gas (nitrogen) in cold or resistance Welding according to the applications.
Frequency range is 4 to 250 MHz.

Crystal Resonators for Defense Applications

Defense Applications:
These resonators are typically suited for radars, telecommunications or munitions applications.

They have a large temperature range and high stability in harsh mechanical environments.

Technical details:   high reliability large temperature range (-55°C to +125°C) stability in harsh mechanical environments low phase noise low g-sensitivity (<3.10-10/g)
