Signal power combiner and divider

摘要

A circuit for combining electronic signal power from multiple input ports to a single set of output terminals or for dividing a single signal at a set of input terminals and providing it to multiple output ports. The circuit has a three-winding transformer and a balance resistor or resistors corresponding to each of the multiple ports. Each port is connected to a first winding of its corresponding transformer. The second windings of the transformers are connected together and to the single set of terminals. Third windings of the transformers are connected together through their corresponding balance resistors.
