Power dividers, also called power splitters, have multiple input and output ports that can be used in reverse, called power combiners or directional couplers, and are primarily designed to direct a specific amount of energy to another circuit. These passive devices are used most often in radio technology but can also be used to monitor energy in transmission lines for a variety of equipment types in almost every field.
Radio Wave Technology
In the field of radio technology, high power dividers can be used to separate the energy from a power transmission line and direct each flow to separate components of the radio. These can also be used in reverse to combine weaker transmission lines from an antenna for better quality. Most people have microwave and radio appliances with one or more directional couplers or dividers in their homes.
Directional couplers and power splitters are also used to monitor the flow and strength of transmission lines without interrupting the signal in multiple types of systems. This can be used to monitor fluctuations in the power supply to medical equipment, oil and gas drilling and much more. When used for monitoring power, dividers have one port connected to the energy transmission lines, one to the equipment components being powered, and two ports connected to a monitoring device. The monitor will pass the energy from the divider through its system and back into the directional coupler to be added back to the mainline.
Couplers and dividers work by channeling energy and signals from transmission lines to other components with a modified amount of energy. Couplers will combine two or more input lines into a single output while dividers will do the opposite. These components are used primarily in the field of radio wave technology but can be used to monitor power supply lines in other fields.
