The full name of the SMA Wilkinson power Splitter is a micro-strip power divider. It is a device that divides the energy of one input signal into two or more outputs with equal or unequal energy; it can also conversely synthesize the energy of multiple signals into one output. At this time, it is also called a combiner, which has the advantages of wide operating frequency, small insertion loss, high gain and isolation, and stable performance.
