Alternate Versions of RF Connectors

Alternate Versions of RF Connectors

Radio frequency (RF) connectors seek to transfer data across multi-megahertz radio frequencies with minimal data loss from reflection and dispersion, in a cost-effective manner.

You may know SMA, RP-SMA, and N connectors. SMA are conventionally used for lower power transmissions, while N connectors for medium power transmissions.




Newer designs that are aimed to improve convenience are now available.

QMA connectors and QN connectors are quick-connect versions of the SMA and N connectors. The goal of the Q type connectors as below:

  1. replace the traditional threaded connection of SMA and N with a snap-fastening to allow for faster mating and de-mating
  1. decrease the overall size of the connector while still matching the electronic performance and reliability of their extremely popular predecessors
  1. allow for 360° cable rotation after installation in order to make cable routing easier

A sample router with the QMA type connector is the peplink's MAX-MBX-MINI 5G router.

Fakra connectors, another new entrant, are SMB based automotive-grade connectors. They have been designed to meet the rigorous mechanical and environmental requirements of the automotive industry.

FAKRA connectors feature specific color-coded plastic housings following a FAKRA coding industry standard for easy identification and mis-matching prevention.


Some of the equipment using FAKRA connectors that are suitable for RV applications and other automobile applications include the sierra wireless XR90 and XR80 5G routers.
