Gore part numbers consist of a minimum of 12 and a maximum of 15 alphanumeric characters. Groupings of these characters have a specific meaning.

When it comes to long-length microwave coaxial assemblies, their phase/loss stability and repeatability, as well as shielding effectiveness, have historically not been well documented. This is largely due to the low demand for these types of assemblies and lack of standardized testing procedures. Published by W. L. Gore & Associates, White Paper: Phase Stability, Loss Stability and Shielding Effectiveness of Long Length provides some much-needed insights into this type of equipment to help operators, engineers and manufacturers find the right extended-length solutions.

The importance of a microwave cable assembly’s shielding effectiveness cannot be understated. Across defense, civil, and aerospace applications, it impacts the system performance of the aircraft and could impede upon data transmission capabilities.

Performance you can gain at the price you can afford. The new benchmark products for high density interconnection, not only for RF and uW modular applications but also for high speed digital test.

Gore provides high-performance cable assemblies with significant mechanical and electrical advantages for high-flex applications in aerospace and defense, spaceflight, semiconductor, and test and measurement environments.

Part numbers consist of 12 alphanumeric characters. The grouping of these characters has a specific meaning. The part number includes cable type, connector types, and assembly length.

SMA, 3.5 mm and 2.92 mm connectors make reliable, RF components and instrumentation possible. These seemingly mundane devices are the result of evolutionary and revolutionary design, covering a 40-year period and involving several corporations. In their present state, they represent highly evolved, well-defined interface systems.
