 The
piezoelectric filters own to the wide family of the electric filters.
They have a very important place because of the intrinsic qualities
of the row materials used for this design : mainly quartz crystal
(SiO2) and lithium tantalate (Li Ta O3).
Their
wide range of performances, combined with their compact size and
costs ratio allow their use in a lot of application for frequency
selection or rejection.
A.R.Electronique is specialized for the engineering and the manufacturing
of specific filters, designed under customer's requirements.
A.R.Electronique filters product range covers civil as well as military
or avionic applications, with harsh environmental requirements,
such as extended temperature range, vibration, shock…
All A.R.Electronique filters integrate crystal resonators internally
designed and manufactured. These internal facilities allow to develop
state of the art devices with a very high reliability level under
short delivery times.
