Overview
Military aircraft applications like inside-the-box and between-the-box systems often use traditionally designed flexible cables such as RG or semi-rigid cable assemblies that are somewhat stiff and difficult to route in confined areas. They can frequently fail and are difficult to replace — often involving costly configuration drawings, challenging installation procedures that are time-consuming, and longer aircraft downtime.
The military needs a more flexible cable assembly option that won’t break or fail during routing and can last over time to keep aircraft in operation longer and save money overall.
High Flexure with Stable Performance
GORE Microwave/RF Assemblies offer extremely flexible options that are proven to survive the rigors of handling and routing in tight configurations while maintaining low insertion loss, reliable VSWR and consistent phase/amplitude stability.
With a tight bend radius, aircraft maintainers will find our assemblies much easier to route in small, constricted spaces. They have a lightweight construction that’s more durable, so they’ll last as long as the aircraft stays in operation.
Consistent Performance Over Time
We offer a broad selection of interconnects operating at frequencies up to 67 gigahertz (GHz) that are well suited for many general purpose applications. Built with a unique proprietary insulation material, they deliver excellent electrical performance consistently over time while maintaining an impedance of 50 +/- 1 ohms to exceed typical industry standards.
Our assemblies also provide outstanding shielding effectiveness through 18 GHz at more than 90 dB. Since the connector choice determines a specific assembly's shielding effectiveness, we also offer a broad selection of connectors designed precisely for use with our assemblies. These connectors are engineered to complement the performance of each cable type, minimizing loss and reflection for optimized signal transmission.
GORE Microwave/RF Assemblies for general purpose applications are proven to maintain exceptional signal integrity with outstanding shielding effectiveness for longer service life, reduced aircraft downtime, and lower total cost of ownership for the military.
