Overview
The aerospace environment routinely exposes microwave/RF assemblies to harsh contaminants such as fuels, oils, and chemicals that can quickly degrade aircraft structures and cause assembly failure in sensitive avionics. In fact, globally more than 75% of microwave/RF assemblies are frequently replaced because of damage during installation or operation according to our independent studies and research. Costs can quickly add up with replacing assemblies, extra labor, and more maintenance and downtime!
VAPOR-SEALED FOR DURABLE PERFORMANCE
GORE Microwave/RF Assemblies, 7 Series is engineered precisely to prevent the ingress of water vapor, fuel, and other hazardous contaminants. They routinely maintain low insertion/return loss and excellent phase stability at frequencies up to 18 gigahertz (GHz).
Not only that, our robust assemblies provide outstanding shielding effectiveness against electromagnetic interference that can compromise signal integrity and reduce the quality of signal transmission. We also offer robust, low-profile connector options designed specifically to complement assembly performance, minimizing loss and reflection for optimized signal transmission.
When it comes to installation, aircraft maintainers will find it much easier to route our assemblies in confined areas because they’re smaller and more flexible with a tighter bend radius. You can be confident that our 7 Series won’t break or fail during routing, like other standard assemblies that are more rigid.
The 7 Series is thoroughly tested and qualified with approved aerospace materials for commercial airborne applications. All of this means superior performance over the aircraft’s lifetime, fewer replacements, reduced system downtime, and lower total costs.
