Information
Reverse polarity SMA connectors (RP-SMA or RSMA) are non-standard versions of SMA Cable connectors. The main application for reverse polarity SMA connectors is WLAN based on the regulations of FCC. SMA cable or SMA female PCB type are connecting between WLAN components.
This SMA right angle plug (Male) can combine with RF coaxial cable from 0.81mm, 1.13mm, 1.32mm, 1.37mm, 1.48mm, to RG178. RP SMA connector has 50 ohm impedance, and it offers excellent electrical performance up to 18 GHz.
Wellshow not only can provide you RP SMA right angle gold plug, but also RP SMA right angle nickel type. If you want to cost down, RP SMA Connector right angle nickel plug will be your best option.
If you need same RP right angle SMA male but for thicker coaxial cable like RG58, RG174, RG316, please link here.

Cable Assembly
Cable assembly Instructions Crimp type
Step1. All parts of RP SMA 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 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.
