Abstract
The utility model relates to a microwave broad band power divider based on a Wilkinson power divider. The microstrip lines are the round topological structures which are connected for the front and the back, and the round topological structures are two-stage connections. The utility model has the advantages that: the round topological structures reduce the coupling between the microstrip lines, simultaneously has no problem of discontinuity around the corner, and the two-stage round topological structures increase the band width, and simultaneously guarantees the coupling reduction between the stages.
Description
Technical field
The utility model relates to a kind of microwave broadband power splitter, particularly a kind of microwave broadband power splitter based on the Wilkinson power splitter.
Background technology
Tradition Wilkinson (Wilkinson) power splitter limited bandwidth has only 10% bandwidth, and topological structure also constitutes rectangular configuration with the straight microstrip line of 1/4 wavelength, and during increase frequency, area is corresponding to be reduced, and coupling influences each other bigger between microstrip line.
Summary of the invention
Technical problem of the present utility model is that a kind of increase frequency that overcomes will be provided, shortened wavelengths causes power splitter undersized, coupling increases between microstrip line, change 1/4 wavelength microstrip line into 3/4 wavelength microstrip line, in order to increase bandwidth, increase the microwave broadband power splitter based on the Wilkinson power splitter of power splitter progression.
In order to solve above technical problem, the utility model provides a kind of microwave broadband power splitter based on the Wilkinson power splitter, and its 3/4 wavelength microstrip line is the circular topology structure, and connects before and after the circular topology structure.The circular topology structure reduces the coupling between microstrip line, does not have the rectangle topology structure problem of discontinuity around the corner simultaneously.
Described circular topology structure is the two-stage cascade.Two-stage circular topology structure increases bandwidth, and the circular topology structure guarantees that interstage coupling reduces simultaneously.
The utility model directly is printed in the PCB printed board.
Superior effect of the present utility model is: changes the topological structure of microstrip line into the circular topology structure, and increases progression, bandwidth is reached about 50%, and the problem of reduced to be coupled between microstrip line influence and turning discontinuity.
