1. A power splitter comprising:
a common port;
a first port;
a second port;
a first phase shifter connected between the common port and the first port; and
a second phase shifter connected between the common port and the second port; wherein
the first phase shifter includes a first capacitor connected in series between the common port and the first port, a first inductor connected between the common port, an end portion at the common port side of the first capacitor, and ground, and a second inductor connected between the first port, an end portion at the first port side of the first capacitor, and the ground;
the first inductor is magnetically coupled to the second inductor;
the second phase shifter includes a second capacitor connected in series between the common port and the second port, a third inductor connected between the common port, an end portion at the common port side of the second capacitor, and the ground, and a fourth inductor connected between the second port, an end portion at the second port side of the second capacitor, and the ground; and
the third inductor is magnetically coupled to the fourth inductor.
