Fig. 2 is a kind of pectination duplexer of the invention comprising:
Shell 1, side are connected with signal port 2, and top is provided with cover board 7；
Pectinate texture 5 is fixed on inside the shell 1, is connect with the signal port 2, and is closed by the cover board 7；
Fixture nut 3, is fixed on the upper surface of the cover board 7, and the lower section of the fixture nut 3 is connected with through-hole, the through-hole
Through the cover board 7；
Screw rod 4 is debugged, is protruded into inside the shell 1 across the through-hole by the upper surface of the cover board 7, the debugging screw rod 4
Top it is fixed by the fixture nut 3.It is set as corresponding ruler and frequency parameter and coupling amount according to duplexer
It is very little, and adjust it and protrude into the depth inside the shell 1, to realize the coupling of 700 MHz of low frequency to high frequency 850MHz.
With reference to Fig. 2 and Fig. 3, inside above-mentioned duplexer, the inside division of the shell 1 is multiple chambers by pectinate texture 5
Body 6.For the coupling parameter of each cavity and resonant parameter are adjusted respectively, the present invention can be described in each of them
Cavity 6 is respectively arranged at least one described debugging screw rod 4.When setting, debugging screw rod 4 corresponding to cavity 6 be may be disposed at
The position at the top 1/3 of pectinate texture 5 described in the 6 top distance of cavity.These adjusting screw rods, refering to what is shown in Fig. 4, its lower end
The height in face may be configured as the upper surface not less than the pectinate texture 5.
In addition, to guarantee that part debugging screw rod 4 can also be set as stretching by the performance parameter between above-mentioned cavity, the present invention
Enter inside the pectinate texture 5 between two adjacent cavitys 6, and/or part debugging screw rod 4 is disposed proximate in the signal
The position of port 2.These debugging screw rods 4, refering to what is shown in Fig. 5, it is protruded into and the signal port by the upper surface of the cover board 7
The inside of the pectinate texture 5 of 2 connections.
Screw thread identical with the fixture nut 3 can be arranged in the inner wall of the through-hole in the present invention, so that the two screw thread
It connects, to cooperate the screw thread of debugging 4 outer upper ends of screw rod, debugging screw rod 4 is fixed, guarantees that it will not be after debugging
It is subjected to displacement, influences device performance.
The present invention will debug screw rod and be transferred to its top by the side of duplexer.Due to being simple cover board at the top of duplexer
Structure, therefore, the fixed fixture nut of punching is than the position aperture difficult processing in side close to pectinate texture on the cover board
It spends smaller.Further, since cover area is bigger, more debugging screw rods can be arranged in the present invention on it, to be directed to duplexer
Performance parameter between the performance parameter and neighboring chambers of each internal cavity carries out debugging one by one, and debugging is more
Accurately.Also, its debugging process of duplexer provided by the present invention does not need to erect device, whole process
Equal retainer member faces up, cover board is upward, and therefore, processing, debugging process are more smoothly, easily operated.Further, since double
It is smaller perpendicular to coupling amount on the direction of pectinate texture in work device, compared to original big coupling amount debugging side along pectinate texture direction
Formula, debugging screw rod of the invention adjust the size of such as 5,6mm, and the influence to performance parameter is equivalent to original big coupling amount shape
The depth that screw rod turns 3mm is debugged under state.Due to adjusting same performance parameter area, the present invention can be turned debugging screw rod more
Big depth, this commissioning staff's operation of being more convenient for.The present invention can avoid slightly rotating debugging screw rod just general in existing debugging process
Device parameter performance debugs to exceed the situation of setting range, is more advantageous to debugging operations.
The present invention is arranged by that will debug screw rod in duplexer upper surface as a result, can: 1 makes cavity, and the processing is simple, no
Multi-panel is needed to process；2. making producing line debugging simple, it is suitble to batch；3. reducing debugging corresponding to debugging screw rod unit sizes
Energy parameter area, facilitates debugging operations, avoids size debugging excessive.
The above is only embodiments of the present invention, and the description thereof is more specific and detailed, and but it cannot be understood as right
The limitation of the invention patent range.It should be pointed out that for those of ordinary skill in the art, not departing from the present invention
Under the premise of design, various modifications and improvements can be made, these are all belonged to the scope of protection of the present invention.
