Abstract
The utility model discloses a novel cavity low-pass prototype power divider. The novel cavity low-pass prototype power divider comprises a shielding box, wherein one end of the shielding box is closed, the unclosed end of the shielding box is used as a power input end, and the upper and lower surfaces of the closed end of the shielding box are respectively provided with one through hole as first and second power output ends; the power input end and the first and second power output ends are respectively provided with a connector, a three-interface power distribution connector is arranged between the two connectors of the first power output end and the second power output end; upper and lower interfaces of the power distribution connector are respectively connected to the connectors of the first and second power output ends, multiple impedance transformers 2 are connected between a third interface of the power distribution connector and the connector of the power input end, and the multiple impedance transformers 2 are interconnected via impedance matching connectors. The novel cavity low-pass prototype power divider has the advantages of being flexible, capable of solving the system mismatching phenomenon, convenient for organizing communication networks, and so on.
Description
Technical field
The utility model relates generally to the communications field, relates in particular to a kind of novel cavity low-pass prototype power splitter.
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 phenomenon of system mismatch appears in existing power splitter easily.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of flexibility that has to be provided, but the resolution system mismatch phenomenon is convenient to the novel cavity low-pass prototype power splitter that communication network is set up.
The utility model is achieved through the following technical solutions:
Novel cavity low-pass prototype power splitter, include a shielding box, it is characterized in that: the end sealing of described shielding box, an end that does not seal of shielding box is as the power input, one end upper of the sealing of shielding box, below on have a through hole as first, the second power take-off, described power input and first, the second power take-off is separately installed with a joint, first, be provided with the power division joint of three interfaces between two joints of the second power take-off, power division joint upper, lower two interfaces receive first by an impedance transformer one respectively, on the joint of the second power take-off, be connected with a plurality of impedance transformers two between the 3rd interface of power division joint and the joint of power input, a plurality of impedance transformers two connect by the impedance matching joint between mutually.
Described impedance transformer two is set with a dismountable annular brace post with the junction of impedance matching joint, and the annular brace post does not seal.
The utility model has the advantages that:
The utlity model has flexibility, but resolution system mismatch phenomenon, 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; And be used in the different frequency scope, for low frequency comparatively significantly volume can accomplish conventional volume 1/2 in addition less.
