Description
Technical field
This utility model is related to household appliance technical field, more particularly to the work(of the multilevel branch structure of a kind of high reliability point
Device.
Background technology
Wilkinson power divider/synthesizers of the prior art, although it adopts multi-section structure to obtain wider work
Make frequency band and higher isolation, but its shortcoming with the increase of joint number, its insertion loss is consequently increased rapidly, and result in power
Distribution and the efficiency for synthesizing are substantially reduced；Further, since power distribution loop overlaps with separate loop in the structure, inside loop
Isolation resistance limited by overall structure size, it is impossible to accomplish increasing heat radiation area, therefore, power capacity is subject to very day of one's doom
System.If all the way amplifier is damaged, or in two branch roads any one branch road port match it is bad when, the reflection of its port
Electromagnetic wave is added to the power at isolation resistance two ends and increases therewith, therefore it is difficult to ensure that isolation resistance is not burned out because high-power,
Although cost can increased by the way that the film resistor on microstrip circuit is replaced by into thick-film resistor to increase its power capacity
While, radiating efficiency is hardly resulted in and effectively improved, so as to result in structure reliability in high power work or port mismatch
Property is substantially reduced.
Utility model content
This utility model provides a kind of power splitter of the multilevel branch structure of high reliability, in solving prior art
Wilkinson power dividers it is difficult to ensure that isolation resistance because high-power technical problem that is not being burned out.
The purpose of this utility model is achieved through the following technical solutions：
A kind of power splitter of the multilevel branch structure of high reliability, including：1 input port, N number of output port, 2N-2
Bar microstrip line and N-1 shading ring, wherein, N is natural number, and the input port is connected by multilevel hierarchy with the output port
Connect, the multilevel hierarchy is power distribution ring per first nodes, and by 1 the first microstrip line 1 even higher level of node is connected, by the
Two microstrip lines 2 and the 3rd microstrip line 3 connect 2 nodes of next stage, and a shading ring 4 is connected across second microstrip line
And the 3rd microstrip line between.
Technique effect of the present utility model is：
