Glossary  >  Splitter



A splitter is a multi-port electronic device used to split radio frequency (RF) signals into two or more ports. Splitting a signal through a splitter results in signal loss as the signal strength is divided among the number of exit ports.

For example, running a signal through a two-way splitter typically results in each output signal having about half the signal strength of the original signal. Minimal loss is also caused by the electronic components within the splitter.

In some applications, the loss of signal strength can cause intermittent loss of service, and in some cases, complete service failure. Thankfully, this is easily mitigated through the use of an amplifier or signal booster.

Splitters are sometimes referred to as combiners, which can be confusing. After all, a combiner does the exact opposite of a splitter. However, unless engineered differently, splitters are usually bidirectional and can be used as combiners, depending on the direction of signal flow.

In this instance, multiple signals would flow into the splitter/combiner and join to create a “new” signal at the exit port.

Example of Splitter in a sentence

"The best-rated splitters usually have a 75 Ohm rating. They help prevent unnecessary signal loss and attenuation."

Synonyms: divider, combiner
