1. A power divider, comprising:
M power division units, wherein the M power division units are cascade connected to form a cascade structure of N levels, wherein each of the power division units comprises one input port and two output ports, and each power division unit in a Kth level in the cascade structure satisfies relationships in which:
input impedance of the power division unit in the Kth level conjugate-matches output impedance of a unit connected to an input port of the power division unit in the Kth level, and output impedance of the power division unit in the Kth level conjugate-matches load impedance of the power division unit in the Kth level, where N, K, and M are positive integers greater than or equal to 1;
M impedance isolation units, each of the M impedance isolation units connected between the two output ports of corresponding power division unit, wherein each of the M impedance isolation units is configured to regulate output impedance of the corresponding power division unit so that the output impedance of the corresponding power division unit conjugate-matches load impedance of the corresponding power division unit.
