What is the difference between coupler and splitter?

The way we define it, a coupler (usually) has four ports, uses no "internal" resistors and has one isolated port that is terminated. A splitter is (usually) a three-port, is non-directional, and requires internal resistors (like a Wilkinson) and has no isolated port.

What does a combiner do in RF?

RF combiners and dividers, also known as combiners and splitters, are multi-port devices and modules that combine or split RF signals between a single port and the other ports. These include active splitters, flux coupled baluns, Wilkinson splitter/combiners and Doherty combiners.

Can a power splitter be used as a combiner?

Since the 0° power splitter is a reciprocal passive device it may be used as a power combiner simply by applying each signal singularly into each of the splitter output ports. The vector sum of the signals will appear as a single output at the splitter input port.

What is combiner in telecom?

Combiners are used to combine two or more inputs signals. Combiners are designed handle high power. It also provides high isolation between ports. to so that a single feed and antenna can be used for the radiating the signals. Combiners are used to reduce the number of antennas and feeders in Base Stations.
