Combiners and splitters (CS) are very useful devices in receive and transmit applications where signals need to be combined (from several antennas for example)or signals need to be split (into two amplifiers for example). They can provide equal voltages, equal current, or equal power to matched or unmatched loads. How it works depends on the product selected.
