Directional Couplers

TRM offers three and four port directional couplers, and dual directional couplers which are realized by using lumped element, airline or stripline technology.

Employing these circuit competencies individually or by combination, allow us to provide an optimal solution for octave and multi-octave frequency coverage from 1 MHz to 26.5 GHz.

We also offer a complete range of narrow band units designed to dependably satisfy the requirements of application specific market segments. Available component packages include pin, surface mount, and connectorized configurations. 

MIL-C-39012 compliant.

Using our Directional Coupler as a baseline, we have the ability to design and manufacture a custom solution for your specific electrical, mechanical and environmental requirements. 

Send your requirements to info@trmmicrowave.com and allow us to offer an innovative, application specific solution.
