System Components

System components are comprised of power dividers, couplers and filters that are used to direct the energy flow for specific frequency bands. The term 'Power Divider' refers to devices meant to distribute power to a number of outputs. A power divider has a single input port and more than one output port. It is typical, although not mandatory, for the transmission from the input to be identical at each output.

A directional coupler is a four-port network with directionality dependent on internal symmetry and matching. It also samples signal energy based on the direction of energy flow. Couplers are commonly used for sampling a portion of the signal that is propagating on the transmission line.
