Abstract
The utility model is applicable to the technical field of communication, and provides a broadband micro-strip three-way power splitter. The broadband micro-strip three-way power splitter comprises a cavity, an input interface, three output interfaces, a micro-strip circuit board arranged in the cavity and a three-way micro-strip circuit arranged on the micro-strip circuit board; the two ports of each micro-strip circuit arranged in the cavity are respectively connected with the input interface and an output interface; and a resistor is arranged between two joints of circuit of every two micro-strip circuits. The broadband micro-strip three-way power splitter has the advantages of wider band, high isolation and high consistency.
Description
Technical field
The utility model belongs to communication technical field, relates in particular to little three power splitters of being with of a kind of wideband.
Background technology
In the wireless mobile communications field, power splitter has obtained using widely, but development along with mobile communications industry, band radio communication is more and more, more and more wideer, existing wideband power splitter can not satisfy actual needs, and especially aspect indoor distribution, this contradiction is more outstanding; Thereby, more extremely industry concern of the design of wideband section, high-isolation, high conforming wideband power splitter.
The utility model content
The utility model embodiment technical problem to be solved is to provide a kind of more wideband section, high-isolation, little three power splitters of being with of high conforming wideband.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of wideband little three power splitters of being with, comprise cavity, an input interface and three output interfaces, described wideband is little also to be comprised with three power splitters: the microstripline plate that is positioned at described cavity, be arranged on three road microstriplines on the described microstripline plate, the two-port that is positioned at the described microstripline in every road of described cavity is connected with an input interface and an output interface respectively, all is connected with resistance between two nodel line roads of every two-way microstripline.
Described three output interfaces lay respectively at the not homonymy of described cavity.
The circuit that the described microstripline in every road all has at least four joint thicknesses not wait.
In the utility model embodiment, by on the microstripline plate, microstripline being set, thereby realized high consistency, and widened the bandwidth of operation of power splitter, be widened to 800-3500MHz by original 800-2500MHz, satisfied now and in following a period of time in the wireless mobile communications field to the demand of wideband power splitter; Owing between each nodel line road of microstripline, all be connected with resistance, thereby realized high-isolation; Because three output interfaces are arranged at the not homonymy of cavity respectively, thereby make interface easy for installation, accomplish minimizing of cavity size simultaneously, meet the modern product miniaturization of being advocated, the requirement of lightness.
Description of drawings
Fig. 1 is the little structural representation with three power splitters of wideband that the utility model embodiment provides.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, little three power splitters of being with of wideband that provide for the utility model embodiment, little three power splitters of being with of described wideband comprise: cavity 1, one input interface 3 and three output interfaces 4, be positioned at the microstripline plate 5 of described cavity 1, be arranged on three road microstriplines 6 on the described microstripline plate 5, the two-port that is positioned at the described microstripline 6 in every road of described cavity 1 is connected with an input interface 3 and an output interface 4 respectively, described three output interfaces 4 lay respectively at the not homonymy of cavity 1, all are connected with resistance 7 between two nodel line roads of the described microstripline 6 of every two-way.In the present embodiment, the circuit that the described microstripline 6 in every road all has at least four joint thicknesses not wait, its effective spread bandwidth satisfies the little performance requirement with three power splitters of this wideband.As the utility model most preferred embodiment, the circuit that the described microstripline 6 in every road all has four joint thicknesses not wait, at this moment, its bandwidth, loss, size, weight all reach best effect.
The utility model embodiment is by being provided with microstripline on the microstripline plate, thereby realized high consistency, and widened the bandwidth of operation of power splitter, be widened to 800-3500MHz by original 800-2500MHz, satisfied now and in following a period of time in the wireless mobile communications field to the demand of wideband power splitter; Owing between each nodel line road of microstripline, all be connected with resistance, thereby realized high-isolation; Because three output interfaces are arranged at the not homonymy of cavity respectively, thereby make interface easy for installation, accomplish minimizing of cavity size simultaneously, meet the modern product miniaturization of being advocated, the requirement of lightness.
As from the foregoing, the utility model embodiment provides more wideband section, high-isolation, little three power splitters of being with of high conforming wideband, its design not only comprises existing main flow communication frequency band, but also has comprised the main flow communication frequency band of following a period of time, as LTE etc.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
