Operational Description - Although the term "power divider" has been applied to various devices meant to distribute power to a number of outputs, the term power divider here is used in a more restricted sense. A power divider has a single designated input port and more than one output port. All ports are theoretically matched and output ports are isolated from one another. It is usual, but not mandatory, for the transmission from the input port to be identical to all output ports. TRM applies the best use of stripline, coaxial, microstrip, Airstrip™ and lumped element circuit topographies in our power divider designs.
