In microwave circuit, in order to power is divided into two-way or multichannel according to a certain percentage, need to use power divider.It is exactly power combiner that power divider uses conversely, so usual power divider/synthesizer is referred to as power splitter.In the power amplifier of the solid-state emission source of microwave high power in modern age, use power divider widely, and power divider is often paired use, first power is divided into some parts, then amplifies respectively, then synthesize output.
Wilkinson power divider all mates due to all of the port, low-loss, high-isolation, advantages such as homophase N port and obtaining use widely, but design conventionally, as Fig. 1, shown in Fig. 2, when same substrate material, raise with operating frequency, operation wavelength shortens, namely λ/4 also shorten, for Ku section f=14.5GHz, wavelength X=20.69mm, λ/4=5.17mm, annulus girth in obvious figure equals 2 × λ/4 and adds isolation resistance A/F again, isolation resistance generally adopts microband paste resistance, the length of Chip-R is 2mm, the radius that therefore can calculate annulus is about 1.96mm, along with operating frequency raises, the radius of annulus is more and more less, the long limit of Chip-R has exceeded the diameter of annulus, there is no enough space mounting Chip-Rs, now paster resistance be assembled into a huge difficult problem, even cannot assemble, even if microband paste resistance A/F is about disregarded suddenly, along with operating frequency rising condition is also like this.

Phase matched problem:
When signal returns the annulus joint of port 2 again by the node (distance is λ/2) of the annulus node arrival Chip-R of port 2, the distance that signal is passed by is just in time λ that is 360 °, and phase place is mated completely.
In like manner, when signal returns the annulus joint of port 3 again by the node of the annulus node arrival Chip-R of port 3, the distance that signal is passed by is just in time also λ that is 360 °, and phase place is mated completely.
By modeling and simulating under microwave electromagnetic simulation software CST environment, the utility model indices, compared with the microstrip power divider indices designed by prior art, is totally better than the microstrip power divider index of prior art design.
