Information
SMA (SubMiniature version A) connectors are coaxial RF connectors developed in the 1960s for coaxial cable with thread mating. The SMA connector has 50 ohm impedance. It offers excellent electrical performance from DC to 18 GHz.
This SMA right angle plug can combine with RF coaxial cable from 0.81mm, 1.13mm, 1.32mm, 1.37mm, 1.48mm, to RG178. If you want to use SMA right angle plug to match with thicker RF cable than the above, please link here.
SMA male connector has the 8mm hex coupling nut. Because RF SMA Connectors are compact in size and have outstanding durability and high-performance, SMA male and SMA female are the most popular RF connector in various application.

Cable Assembly
Cable assembly Instructions Crimp type
Step1. All parts of SMA RF connector are shown as the top line.
Step2. Strip the RF coaxial cable into center conductor, insulator, shielding three parts per recommended stripping dimension shown in SMA RF connector spec.
Step3. Slide the heat shrinking tube on cable jacket, ferrule on cable braid, spacer onto cable dielectric.
Step4. Insert the center conductor into the pin’s slot and solder it, and then push the other parts into main body until it stops.
Step5. Proceed the first open-short test to make sure signal can transmit well.
Step6. Place the insulator then cap on, and press cap into main body.
Step7. Heat shrink the shrinking tube.
Step8. Do the open-short test of every cable assembly before QC examination.
