An SMA-BNC adapter set is a collection of four adapters that are used to connect devices with SMA (SubMiniature version A) connectors to devices with BNC (Bayonet Neill–Concelman) connectors, or vice versa.

SMA connectors are a type of coaxial connector that are commonly used in radio frequency (RF) and microwave applications. They have a small size and a screw-type coupling mechanism, which makes them well-suited for use in tight spaces and high-frequency applications.

BNC connectors are another type of coaxial connector that are often used in RF and microwave applications. They have a bayonet-style coupling mechanism, which allows them to be easily connected and disconnected.

An SMA-BNC adapter set typically includes four adapters, which allow you to connect an SMA connector to a BNC connector, or a BNC connector to an SMA connector. The adapters are typically used to connect devices with different connector types, or to extend the length of a coaxial cable by connecting two cables together.

SMA-BNC adapter sets are often used in a variety of applications, including RF and microwave engineering, electronic test and measurement, and more. They can be a convenient and easy-to-use solution for connecting devices with different connector types, or for extending the length of a coaxial cable.

This set contains 2 different types of Male-To-Female and Female-To-Male BNC-To-SMA adapters
