RP SMA connector male straight solder for RG405 semi rigid, semi flex cable

RP SMA connector male straight solder for RG405 semi rigid, semi flex cable


RP SMA connector is a reverse polarity SMA connector which mean SMA male body will be with female pin, or SMA female body will be with male pin.

SMA RF connector can work up to 18 GHz by soldering with low loss semi rigid or semi flex cable like .047”, RG405 (.085”) or RG402 (.141”). Such kind of high frequency but low loss SMA cable is the first choice to work as RF testing coax cable assembly for testing instrument.

RP SMA RF connector solder male has straight and right angle type (Please link here). It is 50 ohm impedance, and hex coupling nut. 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 plug, and solder through the 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. Do the open-short test of every cable assembly before QC examination.
