Adapter: SMA-female to RP-SMA-female

  • This adapter has an SMA female connector on one end, and has a female RP-SMA connector on the other end.
  • RP-SMA-female end of this adapter has a pin, SMA-female end has a socket.
  • Data Alliance's high-quality soldered terminations of SMA and RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

This antenna cable adapter's range of frequency band compatibility (from 0 to 18GHz) and 50 Ohms impedance matching, makes them suitable and compliant for all the following applications:

RP-SMA-female and SMA-female connectors: Characteristics / Composition:

  • Center Contact: Beryllium Copper, Gold Plated
  • Crimp Ferrule: Copper, Nickel Plated
  • Insulators: PTFE
  • RP-SMA and SMA female Diameter:
    • SMA female outside diameter is 5/16": Accommodates a hex nut (bulkhead nut) with 5/16" nominal outer diameter
    • SMA male inside diameter is 5/16" (the inside diameter where the threads are). In other words, the inside diameter of the hex bolt is 5/16"
    • SMA-female requires a 6.5mm hole
  • RP-SMA and SMA is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.


  • RP-SMA connector fits items that have a (female) RP-SMA (Reverse Polarity SMA) jack/connector. RP-SMA = Reverse Polarity SMA
  • SMA connector fits items that have a (male) SMA jack/connector.

GENDER DETERMINATION: Gender of RP-SMA is counter-intuitive in two ways:

  1. The gender is referring to the pins inside-not the threads. RP-SMA male and SMA male have threads on inside.
  2. "RP" stands for reverse polarization: The pins are female when they appear to be male, and vice versa.
