RF/Coax ConnectorsA simple guide for the perfect fit

TRIMANTEC.COM

RF connectors, or coax connectors, help transmit radio frequency signals by connecting transmission lines to various applications.

THEY'RE MAINLY USED WITH COAXIAL CABLE AND FOUND IN TV RECEIVERS, TWO-WAY RADIO, WI-FI DEVICES WITH ANTENNAS, AND INDUSTRIAL AND SCIENTIFIC MEASURING INSTRUMENTS.

RF CONNECTOR APPLICATIONS

Coaxial CableThe space between the inner and outer conductor is the impedance. The consistency of this measurement is very important to the function of a coaxial cable.

UNDERSTAND HOW COAXIAL CABLE WORKS

CONSTANT IMPEDANCE IS IMPORTANT

This measurement must be the same throughout the entire length of the cable or it can result in signal reflection. When an RF connector is placed at the end of a coaxial cable, the

specifications need to match otherwise the signal cannot be transmitted effectively. 

Key RF connector characteristics include:

Impedance Frequency Range Power Handling

Size Cost
