Information
Besides standard SMA connector male, we also have RP, reverse polarity SMA connector male. RP SMA Coax connector is also a precision coaxial connector for microwave applications, especially is for WLAN application.
RP SMA RF connectors have a thread interface and 50 ohm impedance just like N, FME, SMA, SMC other RF connectors and so on. It can be crimped with RF coaxial cable from 0.81mm, 1.13mm, 1.32mm, 1.37mm, 1.48mm, to RG178.
RP SMA RF connector also has complete and full product lines than other RF cable connectors. SMA connector is a mature RF connector and has big demands.
If you need same RP SMA male connector but for thicker coaxial cable like RG58, RG174, LMR 400, please link here.

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 cable inner conductor into the contact pin of SMA plug, and solder through the side hole to fix it.
Step5. Push the contact pin and other parts into the main body until it stops.
Step6. Proceed the first open-short test to make sure signal transmit well.
Step7. Crimp the ferrule.
Step8. Wear the heat shrinking tube onto the ferrule and then shrink it.
Step9. Do the open-short test of every cable assembly before QC examination.
