GORE® Microwave RF Assemblies, Vapor Sealed

Vapor-Sealed Assemblies Provide Durable Performance

GORE^® Microwave RF Assemblies are not only vapor-sealed but also provide outstanding shielding effectiveness against EMI that can compromise signal quality and transmission. They routinely maintain low loss and excellent phase stability up to 40 GHz for longer system life, less downtime and reduced total costs.

Improved Mechanical & Electrical Performance

The vapor-sealed version of GORE Microwave RF Assemblies features approved aerospace materials and offers many benefits that improve their overall system performance, like:

durable vapor barrier prevents ingress of water, vapor and hash contaminants
maintains quality signals with low loss and excellent phase stability up to 40 GHz
less RF interference due to outstanding shielding effectiveness
easier installation with smaller diameters, more flexibility and tighter bend radii
longer system life for reduced aircraft downtime and lower total costs
meets stringent industry standards, like MIL-T-81490 and others (Contact Gore for available data)
increased design flexibility with robust, replaceable connector options

Vapor-sealed GORE Microwave RF Assemblies are identified by a 12-character part number designating the cable type, connector types, and assembly lengths.

Positions 1–2: Two-letter code representing each cable type (e.g., 7G, 75, 7E, 7L, 7M).

Positions 3–5: Connector A that attaches to the left side of the cable assembly.

Positions 6–8: Connector B that attaches to the right side of the cable assembly.

Positions 9–12: The assembly length is expressed in inches to the nearest tenth, including zeroes to fill positions if the length is less than three digits. For example, the length of a 24-in assembly is specified as 0240 in the last four digits of the part number.
