Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The phase shifter according to claim 1, wherein
the first phase shift circuit amplifies, when a frequency of the input signal is included in the first frequency band and a phase shift amount of an output signal to the input signal is larger than zero degrees and equal to or smaller than 180 degrees, each of the first signal, the second signal, and the third signal in accordance with the phase shift amount, and outputs a synthesized signal of the amplified first signal, the amplified second signal, and the amplified third signal, and
the second phase shift circuit amplifies, when a frequency of the input signal is included in the second frequency band and a phase shift amount of an output signal to the input signal is larger than 180 degrees and equal to or smaller than 360 degrees, each of the first signal, the third signal, and the fourth signal in accordance with the phase shift amount, and outputs a synthesized signal of the amplified first signal, the amplified third signal, and the amplified fourth signal.
