Abstract
The utility model provides an N-type 700-3000MHz-frequency used radio frequency coaxial cavity one-two power divider which comprises a power divider cavity (1), inner conductors (2), a right connector (3), a middle connector (4) and a left connector (5), wherein the inner conductors (2) are arranged in the power divider cavity (1); and the right connector (3), the middle connector (4) and the left connector (5) are respectively arranged at the right side, middle and left side of the power divider cavity. The power divider is characterized in that each inner conductor (2) is stepped and comprises three orders; the frequency use range in the power divider reaches 700-3000MHz, and the length is shortened to 160 millimeters; the surfaces of the left and right inner conductors (2) are plated with 3 microns of silver; the surface of the cavity is subjected to conduction sand blasting treatment; and the housings of the right connector (3), the middle connector (4) and the left connector (5) are made of a high-performance copper material, so that a third-order intermodulation value can reach more than 150dBc, thus completely meeting the 3G communication use standard.
Description
Technical field
The utility model relates to two power splitters that radio-frequency communication product uses, and specially refers to radio-frequency (RF) coaxial cavity two power splitters of using with the 3G moving communicating field.
Background technology
The radio-frequency (RF) coaxial chamber power divider is a kind of a kind of multiport microwave network communication products that input signal are divided into equal or unequal several roads power stage.The 3G moving communicating field is more and more high to the requirement of the property indices of radio frequency coaxial cavity power divider at present, a lot of performance index such as third order intermodulation, classification of waterproof are strict, tradition two cavity of power distributor entire length are in 190 millimeter, the partially long installation position is equipped with of cavity length must be asked and the cost height, third order intermodulation can only reach about 120dBc and the frequency scope of application is 800 ~ 2500MHz, can't satisfy present 3G communication instructions for use.
The utility model content
Technical problem to be solved:
Tradition two cavity of power distributor entire length are in 190 millimeter, the partially long installation position is equipped with of cavity length must be asked and the cost height, third order intermodulation can only reach about 120dBc and the frequency scope of application is 800 ~ 2500MHz, can't satisfy present 3G communication instructions for use.
Technical scheme:
In order to overcome the above problems, radio-frequency (RF) coaxial cavity two power splitters that the utility model provides a kind of N-type 700 ~ 3000MHz frequency to use comprise cavity of power distributor 1, inner wire 2, right connector 3, middle connector 4, left connector 5, inner wire 2 are arranged in the cavity of power distributor 1, right connector 3, middle connector 4, left connector 5 are separately positioned on the right of cavity of power distributor, centre and the left side is characterized in that: inner wire 2 is staged, is divided into three rank.
Inner wire electroplating surface 3 μ silver, housing surface adopt the conduction blasting treatment.
The enclosure material high-performance copper material of right connector 3, middle connector 4, left connector 5.
Beneficial effect:
The frequency scope of application reaches 700 ~ 3000MHz in the power splitter, and contraction in length satisfies 3G communication real requirement to 160 millimeter.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing utility model is further described:
Figure one is schematic diagram of the present utility model
Inner wire 2 is arranged in the cavity of power distributor 1, and right connector 3, middle connector 4, left connector 5 are separately positioned on the right of cavity of power distributor, and centre and the left side is characterized in that: inner wire 2 is staged, is divided into three rank.
Inner conductor of power splitter adopts staged, can make the frequency scope of application reach 700 ~ 3000MHz by the quarter-wave principle design, and contraction in length is to 160 millimeter.
Connector shell adopts the high-performance copper material, and electroplating surface 7 μ ternary alloy coatings, and inner wire electroplating surface 3 μ silver, housing surface adopt the conduction blasting treatment, and the third order intermodulation value is reached more than the 150dBc, reaches 3G communication Application standard fully.
Although the utility model with preferred embodiment openly as above; but they are not to limit the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can make various changes or retouch from working as, what therefore protection range of the present utility model should be defined with the application's claim protection range is as the criterion.
