Abstract

The invention relates to the field of communication, in particular to a power divider, an electronic device, a radio frequency front-end device and a power dividing method. The power divider comprises an input port (P1), a first output port (P2) and a second output port (P3), wherein at least two segments of which the characteristic impedances decrease in sequence are connected in series between the input port (P1) and the first and second output ports (P2, P3); each segment comprises transmission lines which are connected in parallel; each parallel transmission line in every segment is connected through a concentrated resistor at the tail end of each segment which is positioned on one side of the first output port (P2) and one side of the second output port (P3); and the resistance of each concentrated resistor increases in sequence from the input port (P1) to the first and second output ports (P2,P3). Due to the adoption of the power divider, the electronic device, the radio frequency device and the power dividing method, ultra-wideband equal power dividing can be realized in a planar circuit mode.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a power distributor, an electronic device, a radio frequency front-end device and a power distribution method. Background technique [0002] Power dividers have important applications in high-gain antenna arrays, high-efficiency Doherty power amplifiers, and broadband balanced amplifiers. In actual radio frequency circuits or systems, the original single-section Wilkinson power divider has certain limitations in operating bandwidth and cannot meet the requirements of 3.1-10.6GHz ultra-wideband (UWB) systems. [0003] In order to solve such problems, in 2007, Dr. Abbosh of Australia proposed the design of an ultra-wideband power divider using a multi-layer coupled line structure, but its structure is complex, and it is difficult to design and manufacture. cost barrier. In 2010, Dr. Song and Dr. Xue from Hong Kong proposed to use multi-layer slot lines to realiz...
