Adaptador coaxial Telegärtner BNC macho para SMA macho, 50 Ohm, DC-4 GHz, latão niquelado J01008A0018

When a BNC cable must connect to an SMA port, the wrong adapter can cause signal loss, reflections, or mechanical mismatch. The Telegärtner J01008A0018 solves this with a precision in-line adapter that converts a BNC male interface to an SMA male interface while maintaining a stable 50 Ω impedance across DC to 4 GHz.

Who is it for

RF technicians, test engineers, and installers who need a reliable, low-loss transition between BNC and SMA systems in laboratory, instrumentation, or antenna setups.
