SMA Type RF Connectors

Please note that you only need to register as a member for the first time.

SMA (Subminiature Type A) connectors are a type of high-performance miniature connector for RF/microwave applications, offering a wide range of frequencies and exceptional durability.

The body is available in stainless steel or brass, depending on the application. The impedance is 50Ω, using a threaded coupling method.
We also offer high-frequency cables when working with bands above 18 GHz. Please inquire for details.

Some SMA type RF connectors are available for purchase from Digi-Key.

Trivia: About Cables

JIS Standard
Japanese Industrial Standards (JIS) compliant cables. The higher the number of the part number, the thicker the cable. "D: 50Ω" and "C: 75Ω" represent the impedance.
MIL Standard
Compliant with US military standards for cables. Begins with the initials "RG" and is also called Mil-Spec.
Micro Coaxial Cables
Micro coaxial cables for attaching to miniature RF connectors such as U.FL.
Semi-flexible
Shape memory coaxial cables can be bent to a certain degree but have high shielding and low loss (attenuation).
Semi-rigid
Coaxial cables with higher shielding and less attenuation than semi-flexible cables using a seamless metal tube.

The small size of the connector enables high-density mounting in a small space for wiring in equipment and for connections between subassemblies and devices that make up the equipment.

We have a line up of products that can be used in the high-frequency band from DC to 18 GHz and measurement cables that can be used up to 25 GHz.

Unlike the Quick-Connect type, the threaded coupling is recommended for a more secured connection.
