Telegärtner BNC Male to SMA Female RF Coaxial Adapter, 50 Ohm, Straight, J01008A0017

Connecting BNC and SMA interfaces often forces you to choose between signal quality and mechanical reliability. This Telegärtner adapter solves that by providing a precise 50-ohm transition between a BNC male and an SMA female connector, maintaining a low VSWR up to 4 GHz.

Who is it for

RF technicians, lab engineers, and radio amateurs who need to adapt test equipment, antennas, or coaxial assemblies without introducing impedance mismatches. It is also suitable for industrial and telecommunications environments where stable, repeatable connections are required.

Main features

• BNC male to SMA female, straight adapter body
