technical field [0001] The invention belongs to the technical field of power splitters, in particular to a three-way power splitter and a control method thereof. Background technique [0002] With the continuous development of science and technology, electromagnetic wave technology has gradually penetrated into all aspects of our lives. An important characteristic of electromagnetic waves is that they can propagate in any medium or vacuum. During the propagation of electromagnetic waves from the transmitting end to the receiving end, the loss of energy directly affects the distance traveled by the electromagnetic signal and the quality of the transmitted signal. [0003] A power divider is a device that divides the energy of one electromagnetic wave input signal into two or multiple output signals.

[0003] A power divider is a device that divides the energy of one electromagnetic wave input signal into two or multiple output signals. After the electromagnetic wave is divided into multiple channels, there is a large gap between the impedance of the input port and the equivalent impedance of multiple output ports, which will cause The input electromagnetic wave is reflected. Due to the reflection of part of the electromagnetic wave, the electromagnetic energy along the propagation direction will be lost accordingly, which seriously affects the distance of electromagnetic signal propagation, the quality of transmitted signal and the sensitivity of reception.
