Abstract
Methods and devices for enhancing performance of a power splitter are presented. According to one aspect, the power splitter is realized via lumped elements that include inductively coupled coils. Values of the lumped elements are based on an equivalent circuit of the power splitter that includes a star topology provided by a mutual inductance connected to a first port of the power splitter and respective inductances of the inductively coupled coils modified by the mutual inductance connected between the mutual inductance and respective second and third ports of the power splitter. A coupling factor of the inductively coupled coils has a magnitude that is in a range from 0.15 to 0.45. The coupling factor is negative. Respective capacitors are connected to the ports of the power splitter. The respective capacitors include switchable capacitors.
