Understanding Connector: SMA


The SMA connector(SubMiniature version A) is a 50 ohm coaxial connector. It is visually similar to an F type connector that is commonly used for audio/video communication, but has different dimensions, mechanical properties and is used for different applications such as RF communications up to 18 GHz. Due to its construction, SMA connectors provide a strong and durable connection that minimizes reflections, limiting attenuation, and makes it a great choice when working with microwave frequencies.

SMA Male Connector

The SMA male connector is identified by inside 1/4″-36 threads and a 5/16″ hex nut. A standard polarity connector will have a male pin.

SMA Male Dimensions

  • Outer Diameter: 6.35mm
  • Inner Diameter: 4.59mm
  • Pin Diameter: .97mm
  • Pin Tip Diameter: .38mm 


SMA Female Connector

The SMA female connector is identified by outside 1/4″-36 threads. A standard polarity connector will have a female sleeve.

SMA Female Dimensions
    • Outer Diameter: 5.49mm
    • Inner Diameter: 4.60mm
    • Pin Insert Diameter: 1.30m



    Reverse Polarity (RP) SMA Male Connector 

    The RP SMA male connector is identified by inside 1/4″-36 threads and a 5/16″ hex nut. It will not have a male pin, but will have a female sleeve.

    RP SMA Male Dimensions

    • Outer Diameter: 6.35mm
    • Inner Diameter: 4.59mm
    • Pin Insert Diameter: 1.30mm



    Reverse Polarity (RP) SMA Female Connector

    The SMA female connector is identified by outside 1/4″-36 threads. A standard polarity connector will not have a female sleeve, but will have a male pin.

    RP SMA Female Dimensions
    • Outer Diameter: 5.49mm
    • Inner Diameter: 4.60mm
    • Pin Diameter: .97mm
    • Pin Tip Diameter: .38mm
