Abstract
The utility model discloses a low insertion loss basic station duplexer, the positive pressure or negative pressure device comprises a cavity, be provided with low pass filter and joint in the cavity, low pass filter is connected through connecting the guide arm with connecting, it is filled with the air dielectric to connect the guide arm intussuseption. The beneficial effects of the utility model reside in that, solved and adopted half gentle rigidity cable junction to lead to the shortcoming that insertion loss is big among the prior art. The utility model discloses consequently, have characteristics such as low insertion loss, low third order intermodulation, high power.
Description
Technical field
This utility model relates to a kind of low insertion loss base station duplexer, belongs to technical field of communication equipment.
Background technology
At present, the duplexer used in prior art generally uses half soft rigidity cable to be connected with the tap of base station duplexer and joint respectively.Half soft rigidity cable insertion loss is big, and general 100 millimeters long half soft rigidity cable insertion loss, at 0.2dB, cause that base station duplexer insertion loss is big.
Summary of the invention
The purpose of this utility model is in that to overcome disadvantages mentioned above, a kind of low insertion loss base station duplexer of design.
In order to realize foregoing invention purpose, this utility model adopts the following technical scheme that
A kind of low insertion loss base station duplexer, including cavity, is provided with low pass filter and joint, described low pass filter and joint and is connected by connecting guide rod, be filled with air dielectric in described connection guide rod in described cavity.
Preferably, described connection guide rod is fixed in cavity by insulator.
Advantage of the present utility model and effect are in that the connection guide rod used adopts air dielectric to fill, and connect guide rod and adopt teflon insulation to be fixed on cavity.Therefore the power that insertion loss is low, third order intermodulation is low, bear is high, assemble the features such as simple.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is partial enlarged drawing of the present utility model.
Wherein, 1 is cavity, and 2 is connect guide rod, and 3 is insulator.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
As depicted in figs. 1 and 2, insulator 3 is set on connection guide rod 2, puts in cavity 1 by connection guide rod 2 afterwards, is fixed in cavity 1 by insulator 3, connecting guide rod 2 end to connect with the joint of duplexer, low pass filter respectively, guide rod is easy to assembly, concordance good in this utility model connection.
Connect guide rod and adopt H59 copper material, electroplate；Connect the insulator used on guide rod and adopt politef.
Connecting guide rod adopts air dielectric to fill；So that connecting mating of guide rod and cavity formation 50 ohm, the connection guide rod insertion loss of 100 mm lengths is 0.012dB.
Claims (2)
