Overview

According to our independent studies and research, globally more than 75% of microwave/RF assemblies are frequently replaced because of damage during installation or operation. That’s a high percentage of assembly failure that involves taking the aircraft out of service, extra labor to replace assemblies, and more money that can add up fast! With more passengers traveling these days for business or leisure, the industry needs avionics to operate reliably and aircraft to remain in service longer.

Proven Performance & Reliability

GORE Microwave/RF Assemblies ensure optimal electrical and mechanical performance consistently for the duration of the aircraft. They deliver dependable signal integrity for superior radio frequency up to 32 gigahertz (GHz) in Ka/Ku-Band applications.

Our assemblies are also proven to provide outstanding shielding effectiveness with excellent insertion/return loss for less RF interference among multiple satellite communications systems. Since the connector choice determines a specific assembly’s shielding effectiveness, we offer an assortment of connectors designed specifically to complement assembly performance, minimizing loss and reflection for optimized signal transmission.

But that’s not all. We combine durability in a small, low-weight construction so that mechanical strength isn't compromised. Our assemblies ensure high-quality signals in harsh environments, like complex routing, maintenance activities, and flight conditions. Their smaller size also means more flexibility, so aircraft maintainers will find them easy to route — particularly for conduit installation or in areas that require little to no maintenance activity.

GORE Microwave/RF Assemblies are proven to maintain high-quality signals with proven shielding effectiveness for longer service life, less downtime, and fewer total costs.
