Abstract

The invention provides a power divider, an adjusting method and a power distribution method. The power divider comprises N power dividing units, the N power dividing units are cascaded to form an M-stage cascade structure, and each power dividing unit comprises an input port and two output ports. A K-th-stage power dividing unit in the cascade structure meets the following relation that the inputimpedance of the K-th-stage power dividing unit is in conjugate match with the output impedance of a unit connected with the input end of the K-th-stage power dividing unit, the output impedance of the K-th-stage power dividing unit is in conjugate match with the load impedance of the K-th-stage power dividing unit, and N, K and M are all positive integers greater than or equal to 1. According tothe invention, the problem that the area of the power divider is large due to the fact that the length of a signal line of the power divider is large in the prior art is solved, the overall area of the power divider is reduced, and the loss of the power divider is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a power divider, an adjustment method and a power distribution method. Background technique [0002] In recent years, mobile communications, electronic countermeasures, and satellite communications are developing toward miniaturization, broadband, and higher operating frequency bands, and the requirements for frequency and bandwidth are also developing toward high-frequency broadband. In the era of rapid development of 5G technology, the millimeter wave frequency band has attracted extensive research due to its characteristics of large bandwidth and high capacity. Since the high-frequency signal will have a large loss during transmission, which will affect the communication quality, it is necessary to apply multi-channel phased array technology, and the power divider (power divider) is an essential part of it. With the demand for integrated miniaturization of radio frequency de...
