Coaxial Adapters

Amphenol RF In-Series and Between-Series Coaxial Adapters are designed to meet the requirements of RF applications. These adapters provide consistent electrical performance and optimized mechanical reliability, as they allow transitions between popular coaxial connector interfaces such as BNC, SMA, N-Type, and TNC. Amphenol RF Coaxial Adapters feature multiple adapter configurations and are available in a variety of body materials, including brass, beryllium copper, and stainless steel.
