1. A power divider comprising one input port and four output ports, the power divider comprising:
an input-terminal inductor configured to have one end connected to the input port and another end connected to a ground;
an inductor group configured to comprise four output-terminal inductors; and
four connectors configured to connect the input port and the inductor group,
wherein the output-terminal inductors are respectively connected to the four connectors so that four nodes are formed between the four connectors and the inductor group,
wherein the output ports are respectively disposed in the four connectors between the input port and the inductor group, and
wherein a value of a quality factor of the input-terminal inductor is greater than a value of each quality factor of the output-terminal inductors.
