Abstract
A multiport splitter with a circuit that is less costly, smaller, impedance matched on all ports, provides 9.54 dB isolation between neighboring ports, and is balanced as compared to the current typical implementations. The present disclosure may further provide a single multiport splitter that may be increased to any suitable number of output ports without the need for cascading multiple splitters and/or couplers together in a single device.
