Abstract
The utility model discloses a novel cavity unequal power divider, which comprises a shielding box. Both ends of the shielding box are not closed; the two ends of the shielding box respectively serve as a power input end and a first power output end; the shielding box is also provided with a through hole which serves as a second power output end; a joint is respectively arranged at the power input end, the first power output end and the second power output end; a plurality of impedance transformers and a power division matching joint are sequentially connected between the two joints of the power input end and the first power output end of the shielding box; the plurality of impedance transformers and the power division matching joint are connected via impedance matching joints; the power division matching joint is provided with a round hole; a power division joint is vertically mounted on the round hole located on the power division matching joint; and the other end of the power division joint is connected onto the joint of the second power output end. The novel cavity unequal power divider disclosed by the utility model is compact in the whole structure, large in power and free in power division; and the novel cavity unequal power divider can be applied to different frequency ranges and different power division ratios.
Description
Technical field
The utility model relates generally to the power splitter field, relates in particular to not five equilibrium power splitter of a kind of novel cavity.
Background technology
Power splitter full name power divider, English name Power divider, a kind ofly one road input signal energy to be divided into the output of two-way or multichannel equates or the device of unequal energy, also can be conversely with synthetic one tunnel output of multiple signals energy, can be also referred to as mixer this moment.Should guarantee certain isolation between the output port of a power splitter.The important technological parameters of power splitter has the voltage standing wave ratio of power loss (comprise insertion loss, distribute loss and reflection loss), each port, the isolation between the power division port, power capacity and frequency bandwidth etc.
The utility model relates to not five equilibrium power splitter of a kind of novel cavity, and the different capacity that is mainly used in China Telecom's each signal port of indoor covering system distributes.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, not five equilibrium power splitter of a kind of novel cavity to be provided.
The utility model is achieved through the following technical solutions:
Novel cavity is the five equilibrium power splitter not, it is characterized in that: include a shielding box, the two ends of described shielding box are not sealed, respectively as power input and the first power take-off, also have a through hole as the second power take-off on the shielding box, described power input and first, the second power take-off is separately installed with a joint, be connected with a plurality of impedance transformers and a power division matched junction in turn between the power input of shielding box and two joints of the first power take-off, a plurality of impedance transformers are connected with the power division matched junction and are connected by the impedance matching joint, have a circular hole on the power division matched junction, be positioned on the circular hole of power division matched junction and be vertically installed with a power division joint, the other end of power division joint is received on the joint of the second power take-off.
Described impedance transformer is determined size according to different frequencies, different performances.
The utility model has the advantages that:
The utility model compact overall structure, processing is simple, and cost is lower, and volume is little lightweight, homogeneity of product is better, and power is large, and intermodulation is high, good stability, it is comparatively convenient to install, and key is that power division is free, is used in the different frequency scope, different power-division ratios.

Fig. 2 is cutaway view of the present utility model.
Embodiment
Such as Fig. 1, shown in 2, novel cavity is the five equilibrium power splitter not, include a shielding box 1, the two ends of shielding box 1 are not sealed, respectively as power input 2 and the first power take-off 3, also have a through hole as the second power take-off 4 on the shielding box 1, power input 2 and first, the second power take-off 3,4 are separately installed with a joint 5, be connected with a plurality of impedance transformers 6 and a power division matched junction 7 in turn between the power input 2 of shielding box 1 and two joints of the first power take-off 3, a plurality of impedance transformers 6 are connected with the power division matched junction each other by 8 connections of impedance matching joint, have a circular hole on the power division matched junction 7, be positioned on the circular hole of power division matched junction 7 and be vertically installed with a power division joint 9, the other end of power division joint 9 is received on the joint 5 of the second power take-off 4.
Impedance transformer 6 is determined size according to different frequencies, different performances.
Power division joint 9 can select different materials to realize according to different distribution ratios; The centre has individual circular hole to be connected with the power division matched junction to connect but can not short circuit.
The utlity model has flexibility, but power five equilibrium problem not between resolution system, be convenient to communication network and set up, the plurality of advantages such as its product shape size is little, be designed beautifully, the signal transmission is unobstructed, each branch power partition equilibrium, power are born height, intermodulation is high, convenient for installation and maintenance.
