There are many types of power dividers, and their design structure is closely related to the operating frequency. The power divider is divided into two categories from the structure:

(1) Passive power divider, its main characteristics are: stable operation, single structure, and basically no noise; and its main disadvantage is that the access loss is too large.

(2) The active power divider consists of an amplifier. Its main characteristics are: gain, high isolation, and its main disadvantages are noise, relatively complicated structure, and relatively poor working stability. The output ports of the power divider include two power points, three power points, four power points, six power points, eight power points, and twelve power points.
