Microwave/RF assemblies are frequently exposed to harsh contaminants like fuels, oils, and chemicals that can quickly degrade vehicle structures and cause assembly failure in mission systems. If a critical system fails, then the entire military unit and operation are at risk.


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 40 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.

When it comes to installation, vehicle 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 fully tested and satisfies the mechanical/environmental requirements of stringent military standards. All of this means superior performance over the vehicle’s operational life, fewer replacements, reduced system downtime, and lower total costs for operators.
