Embodiment Construction

[0024] see figure 1 , figure 1 It is a schematic structural diagram of an ultra-wideband Wilkinson power divider in an embodiment.

[0025] In this embodiment, the ultra-wideband Wilkinson power splitter includes a dielectric layer, a signal metal layer attached to one side of the dielectric layer, and a metal bottom layer attached to the other side of the dielectric layer, and the signal metal layer The layers include microwave transmission branches 11, 12 and microstrip extension junctions 20, 21.

[0026] The microwave transmission branches 11 and 12 are used to divide one microwave signal into multiple microwave branch signals for output.

[0027] A traditional Wilkinson power divider includes a dielectric layer, a signal metal layer attached to one side of the dielectric layer, and a metal bottom layer attached to the other side of the dielectric layer. Such as a two-power splitter, its signal metal layer has two microwave transmission branches 11, 12, and each microwa...

Abstract

The invention relates to an ultra-wide-band Wilkinson power divider, which comprises a dielectric layer, a signal metal layer attached to one side of the dielectric layer, and a metal bottom layer attached to the other side of the dielectric layer. The signal metal layer comprises a microwave transmission branch and a microstrip line expansion structure, wherein the microwave transmission branch is used for dividing a path of microwave signal into multiple paths of microwave branch signals for output; and the microstrip line expansion structure is composed of microstrip lines, one end of the microstrip line expansion structure is connected to the microwave transmission branch, the other end is suspended, the length of each microstrip line is 1 / 4 of central wavelength of microwaves of the ultra-wide-band Wilkinson power divider, and the microstrip line expansion structure is used for increasing polar points of the Wilkinson power divider. Through arranging the microstrip line expansion structure on the microwave transmission branch of the Wilkinson power divider, the polar points of the Wilkinson power divider are increased, and the frequency band thereof can be broadened, thereby acquiring the ultra-wide-band Wilkinson power divider with a simple structure.

Description

technical field [0001] The invention relates to the field of power dividers, in particular to an ultra-wideband Wilkinson power divider. Background technique [0002] Power dividers are widely used in microwave and millimeter wave communication circuits, such as microwave power sensors, mixers, phase detection and TR components, and many other circuits. At present, with the rapid development of wireless communication technology, the wide frequency band and low loss of devices have become research hotspots in microwave radio frequency circuits, and with the research and application of ultra-wideband devices such as ultra-wideband antennas and ultra-wideband filters, ultra-wideband Wideband power splitters are also becoming more and more in demand. [0003] However, the bandwidth of the traditional Wilkinson power splitter is relatively narrow, which seriously restricts the use of the Wilkinson power splitter in the ultra-wideband field. Contents of the invention [0004] ...
