Abstract

The invention discloses a design method of a multi-channel arbitrary power dividing ratio Gysel type power divider. The designed power divider comprises an input port, N output ports, N first-stage transmission lines, N second-stage transmission lines, N grounded isolation resistors and N third-stage transmission lines. The invention can realize arbitrary power distribution ratio, arbitrary outputpath number and power distribution and synthesis of arbitrary port load, and overcomes the defects that the traditional multi-channel Gysel power divider only has the same power distribution ratio and the same port load.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a design method for a multi-channel Gysel type power divider with arbitrary power division ratios. Background technique [0002] The power divider is a device for dividing the amplitude and phase of the input signal, and is widely used in the antenna feeding system. The Wilkinson type power divider is one of the most typical power dividers, but the distributed capacitance effect between the isolation resistor and the floor used in it limits its application in high power applications. The original Gysel power splitter is an improved version of the Wilkinson power splitter proposed by U.H.Gysel in 1975. It has the advantage of large power capacity and can be used in high power applications. [0003] At present, most of the common Gysel power splitters have two outputs; while the multi-output Gysel power splitters mostly distribute power evenly, and are large in size, co...
