Maximum Flexibility, Excellent Electrical Performance

A study showed that globally more than 75% of microwave/RF cable assemblies are replaced frequently due to damage during installation or operation. GOREMicrowave/RF Assemblies are extremely flexible and can withstand the rigors of handling and installation.

Unlike traditionally designed microwave test cables that are stiff and difficult to handle, our assemblies feature a smaller form factor with better flexibility and a tight bend radius without compromising electrical performance. Even in tight spaces, they make routing easy, particularly in board-to-board and inside-the-box applications. Our assemblies simplify system design, maintain signal integrity over longer service life and lower energy consumption.

Instead of replacing standard semi-rigid cables several times a year, choose GORE Microwave/RF Assemblies for improved installation results, longer service life, decreased maintenance of cables, and decreased downtime of cables.

Precise, Repeatable Measurements

Our microwave/RF cable assemblies deliver consistent and excellent electrical performance from DC through 70 GHz. They bring precise and repeatable measurements with proven phase and amplitude stability. We provide cable assemblies with best EMI/EMC performance, delivering a minimum of 100 dB through 18 GHz. Our high-performance cable assemblies with the lowest RF leakage are unmatched by other RF cable assembly manufacturers.

Since a specific assembly’s RF shielding effectiveness is largely influenced by the choice of connector, Gore offers a variety of in-house custom connector types designed specifically for our microwave cables. These connectors are uniquely engineered to enhance the performance of our assemblies with lower loss, reflection and RF leakage for optimized signal transmission under challenging environments.
