RF Terminators

RF terminators are devices used to electrically terminate coaxial RF (radio frequency) ports. They are usually placed at the end of the transmission line to prevent an RF signal from being reflected.

RF terminators are designed to match the surge impedance (ratio of current and voltage) of the cable to help minimise signal reflections and power losses. Unused tap ports or coaxial faceplates in a home, for example, can create entry and exit paths, which affect performance.

How do RF terminators work?

RF terminators absorb the electrical energy of the signal as it reaches the cable ends and prevents the signal from being reflected so it doesn’t become noise. They ensure that current flows smoothly from one device to another.

What are RF terminators used for?

RF terminators play a critical role in high-frequency systems and circuits, especially when managing high-power signals. They can also be used to close open terminations that might otherwise allow parasitic signals to enter the circuit, such as at a T-junction.

RF terminators are available in many form factors with power ratings to match their sizes.
