Background technology
Traditional broadband power divider circuit, in order to obtain enough bandwidth, band is realized using the transmission line technology of more piece λ/4
It is wide；Due to the limitation of the device frequency characteristic of use, often simultaneously it cannot be guaranteed that the miniaturization of device and filter with low insertion loss requirement.
Utility model content
The purpose of this utility model is that providing a kind of 6-18G broadbands one divides three power splitters, to solve above-mentioned background technology
The problem of middle proposition.Three power splitters are divided with good, the isolation with bandwidth input and output reflectance factor in the 6-18G broadbands one
Height, the advantages that insertion loss is small and size is small, there is the characteristics of more apparent lifting compared to traditional circuit indices performance.
To achieve the above object, the utility model provides following technical scheme：
Three power splitters, including two-stage LC impedances conversion section are divided in a kind of 6-18G broadbands one；Included in every grade of LC impedances conversion section
Three signal transmission branches, three signal transmission branches of three signal transmission branches connection neighboring later stage in prime；
Wherein, each signal transmission branch includes after two inductance concatenation again and is connected to electric capacity, and three signal transmission branches are mutual
Mutual isolation resistance, form plane umbrella stand type irradiation structure.
Preferably, three signal transmission branches in previous stage are connected to the input port of signal, in adjacent latter
Three signal transmission branches of level are connected to the output port of signal.
Compared with prior art, the beneficial effects of the utility model are：Section substitution tradition electricity is converted using two-stage LC impedances
The transmission line of the λ on road/4, is greatly reduced power splitter volume, and the inductance element in LC impedances conversion section uses multiple different sizes
Inductance is composed in series, and ensure that, isolation height good with bandwidth input and output reflectance factor, and insertion loss is small and size is small etc.
Advantage, there is more apparent lifting compared to traditional circuit indices performance.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：
Three power splitters, including two-stage LC impedances conversion section are divided in a kind of 6-18G broadbands one, substitute λ/4 of traditional circuit to transmit
Line, it is greatly reduced power splitter volume；Every grade of LC impedance converts and three signal transmission branches is included in section, and three in prime
Three signal transmission branches of individual signal transmission branch connection neighboring later stage, three signal transmission branches in previous stage connect
It is connected to the input port of signal, i.e. P1, three signal transmission branches in neighboring later stage are connected to the output port of signal；
Wherein, each signal transmission branch includes after two inductance concatenation again and is connected to electric capacity, and three signal transmission branches are mutual
Mutual isolation resistance, forms plane umbrella stand type irradiation structure, and LC impedances conversion economize on electricity sensing unit uses multiple different size inductance
It is composed in series, ensure that with relatively low insertion loss and good isolation.
By signal transmission branch exemplified by one of them：Inductance L1、L2With electric capacity C1Form the first signal transmission branch of the first order
Road, another two branch case is consistent, mutual isolation resistance R between three branch roads1、R2And R3In the presence of three branch roads form plane umbrella stand
Type irradiation structure.The second level (neighboring later stage) structure is consistent with front stage circuits, is believed in second level branch road end for 3 roads
Number output port, i.e. inductance L8Even P2, inductance L10Even P3, inductance L12Even P4。
The utility model is further described below in conjunction with Fig. 1：
1st, the L inductance elements in every grade of LC structure are realized using 2 inductance, both ensure that the small size of device or have been ensured
Insertion loss is smaller.
According to Fig. 1 circuit structure, the matching of appropriate numerical value is selected, three power splitters are divided in design 6-18G broadbands one, actual to survey
Test result is referring to Fig. 2-4.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
