General Purpose RF Solutions
for Aircraft

Gore’s durable, highly flexible assemblies are easy to route in very small areas and ensure long-lasting electrical performance after installation. Our small, lightweight assemblies are an ideal replacement for traditional semi-rigid assemblies because they don’t have to be frequently replaced, resulting in lower total costs.

General Purpose Cables for Test Assemblies

Coaxial & Microwave / RF Cable Assemblies

Proving reliable performance with extremely small, flexible assemblies that survive routing in tight spaces.

English (U.S.)

Overview

Today’s inside-the-box defense and aerospace systems use traditional semi-rigid cable assemblies that are stiff and difficult to route in confined spaces, which can lead to frequent cable failure. They are also difficult to replace — a problem that often requires costly configuration drawings and challenging installation procedures that are time-consuming.

Greater Flexibility with Stable Performance

GORE® Microwave/RF Assemblies provide a small, highly flexible assembly option that withstands the rigors of handling and installation while delivering reliable signal integrity for longer service life and lower total costs — making them an ideal replacement for traditional semi-rigid assemblies.

With a tight bend radius, Gore’s assemblies are easier to route in very small configurations in aircraft such as inside-the-box systems. They have a high-density construction that is more durable, yet lighter weight compared to semi-rigid assemblies.

Excellent Electrical Performance
Construction of GORE Microwave/RF Assemblies.

Construction of GORE® Microwave/RF Assemblies.

Our assemblies offer excellent electrical performance in applications from DC through 67 GHz. Gore’s expanded polytetrafluoroethylene (ePTFE) insulation has a dielectric constant of 1.4, which translates to:

•    low relative loss
•    high velocity of propagation (85% speed of light)
•    low capacitive loading
•    high cut-off frequencies

Protected by the inner braid and jacket, the outer conductor delivers a minimum of 100 dB/ft., of shielding effectiveness through 18 GHz. 
Since a specific assembly’s shielding effectiveness is determined by the choice of connector, we offer a variety of standard connectors designed specifically for our assemblies. These connectors are engineered 
to complement the performance of each cable, 
minimizing loss and reflection for optimized 
signal transmission.
 

Applications

GORE Microwave/RF Assemblies are engineered to perform reliably in a variety of civil and military aerospace applications, including:

  • antenna arrays
  • ATE systems (automated test equipment)
  • backplane interconnects
  • board-to-board systems
  • clock distribution
  • environmental test chambers
  • evaluation boards
  • inside-the-box systems
  • load boards
  • module-to-module interconnect
  • optical modules
  • telecommunication systems
  • test bench systems
  • thermal vacuum chambers
  • wafer probing

If you have any questions or to discuss your specific application needs, please contact a Gore representative.

Benefits

GORE Microwave/RF Assemblies provide manufacturers with many benefits that improve electrical and mechanical performance such as:

  • excellent electrical performance in applications from DC through 67 GHz
  • maintains low insertion loss and reliable VSWR up to 18 GHz during flexure
  • outstanding shielding effectiveness through 18 GHz
  • reliable signal integrity for longer service life and lower total costs
  • easy routing in small configurations due to tight bend radius

For more information about the benefits of our cables, please contact a Gore representative.
