For more than 25 years, AR Electronique designs and manufactures in Besançon (France) high performance Frequency & Time devices. The product range covers Xtal resonators (AT cut, SC cut), high stability oscillators (XO, VCXO, TCXO, OCXO), piezoelectric filters (BAW filters, all types), as well as sub systems (frequency sources with miscellaneous characteristics). These products are mainly developed as an answer to specific customer's requirements. They address a lot of RF applications, from laboratory, test equipments, defense / airborne radiocommunication systems, radars up to on-board space domain. They offer state of the art characteristics, in terms of high frequency stability, very low phase noise, as well as improved immunity to environmental conditions (wide temperature range, vibration, acceleration and shock). AR Electronique oscillators cover a frequency range from 5 MHz to 150 MHz (direct frequency), and up to several GHz with the use of internal low noise frequency multipliers. AR Electronique products are 100% in-house manufactured and tested (frequency stability, spectral purity, phase noise, under static and environmental conditions).
