Film Cards

We offer a complete line of standard and custom wave-guide attenuator elements.  Deposition of thin film metalization on a glass substrate with an optical grade finish produces an extremely stable resistive film.  A protective coating is evaporated over the resistive film to prevent oxidation. Controlled processes throughout produce guaranteed repeatability.

Film cards are available in four materials: Fiberglass, Mylar^®, Kapton^® or Mica. They feature a surface resistance range of 25 to 1k ohm per square and power handling up to 8 watts.  Applications include: Waveguide Elements, Crystal Detector Protection, Directional Coupler Termination and Mode Suppression in Cavity Filters.
