Device Overview

General Description

The C10-2800WG is a WR28 10dB waveguide coupler featuring high directivity over a 26.5-40GHz operational bandwidth. These waveguide components are built with high precision and then gold plated for high corrosion resistance. They have very low loss and excellent VSWR. Manufactured to rigid specifications, these transmission line components provide minimum detrimental effects on overall system VSWR.
