Coaxial Connectors & RF Connectors

An RF Coaxial adapter is a single piece component allowing the connection of two different pieces of equipment that cannot be joined directly.

What does it do?

Coaxial adapters provide a convenient method of connecting RF equipment together.


• Laboratory

• Test and measurement

• Communications

• Base stations



• Antennas


There are two main types of RF coaxial adapters;

In series

A two port Interconnection device that provides a convenient method of converting from one gender to another in same series. Is also known as an inline coupler or inline barrel adapter. An In series coaxial adapter is also a handy way to join two lengths of cable together to extend the run within the same connector series.

Between series

A two port interconnection device allowing the conversion between two different types of RF coaxial cable connector types. For example BNC to N, SMA to TNC.

The most important attributes that must be considered are;


• Male to Male

• Female to Female

• Male to Female

Series (connector group)

SMA, BNC, TNC, N type

Body orientation

• Straight

• Right angle

• Tee


• 50 Ω

• 75 Ω
