Low Power Terminations

Low Power Terminations consist of a short section of waveguide containing a precisely tapered element designed to absorb microwave energy with very low VSWR. Our Terminations are available in sizes WR3 to WR42. In addition to the models listed, Terminations with different lengths can be supplied on special order.

Ordering Example:

LT28S is a low power termination in WR28 with a Square Flange.
