of the Art, Inc. (SOTA) offers a broad range of
resistors that are tailored for optimal high frequency
performance. Careful selection of materials, special
designs, and proprietary manufacturing methods result
in devices with minimal losses and reflections.
Thick film resistors are available constructed on
alumina, or beryllia. They are available in all
standard sizes, and are suitable for applications
up to 8GHz. Thin film resistors are available on
alumina and aluminum nitride. They are suitable
for applications up to 40 GHz, and they typically
exhibit VSWR’s of 1.15: up to 2 GHz and 1.25:1
up to 8 GHz. For operating frequencies greater than
12 GHz planar (single surface, termination type
A) are recommended.
High frequency resistors are available in solderable,
epoxy bondable, and wire bondable termination finishes.
High power versions (beryllia or aluminum nitride
substrates) are available as bare chip, leaded chip,
and in flange mount packages. Careful selection
of case size, termination type, and mounting method
will greatly improve the performance of these devices.
A variety of high reliability screening options
are available. Please contact your representative or the factory directly with any questions regarding
