Information
This Reverse Polarity SMA RF connector can work up to 18 GHz by soldering with low loss semi rigid or semi flex cable like RG405 (.085”) or RG402 (.141”). Such kind of high frequency but low loss RP SMA cable is the first choice to work as RF testing coax cable assembly for testing instrument.
RP SMA RF solder right angle plug is 50 ohm impedance. Many customers buy the RP SMA coaxial connector to make SMA cable assembly or RF antennas which are widely used in RF various applications like GPS antenna, GSM antenna and so on.
SMA connectors are widely used in RF various industries. If you only want commercial grade SMA cable connectors, please link the RF SMA connector main webpage to get more choices.

Cable Assembly
Cable assembly Instructions Solder type
Step1. All parts of SMA RF connector are shown as the top line.
Step2. Strip the RF coaxial cable into center conductor and insulator per recommended stripping dimension shown in SMA RF connector spec.
Step3. Insert the cable inner conductor into the contact pin of SMA connector, and solder through the pin’s side hole to fix it.
Step4. Push the contact pin into the main body per SMA interface dimension.
Step5. Encircle the joint of barrel and cable by soldering.
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.
