Abstract
The utility model discloses a low intermodulation resonant column of a combiner, which comprises a resonant column body, wherein the resonant column body comprises a column, a loading disk and a step, the step under the resonant column body is provided with a mounting hole, and all edge angles of the column, the loading disk and the step are reversed obtuse angles. The low intermodulation resonant column of the combiner is used for manufacturing combiners, thereby remarkably reducing the intermodulation values of the combiners.
Description
[technical field]
The utility model relates to mixer, relates in particular to a kind of resonance post that is used for low intermodulation mixer.
[background technology]
China's existing mobile communication network has entered the 3G epoch, and communication system has mobile GSM900, the GSM900 of UNICOM, mobile DCS1800, the DCS1800 of UNICOM, TD-SCDMA, WCDMA, CDMA800, CDMA2000, PHS, WLAN, Digital Clustering and other communication systems; Frequency band by each system cut apart more and more thinner, Frequency point is also more and more approaching, the frequent road, along separate routes of closing causes parasitic passband also more and more between each system, and high third order intermodulation, five rank intermodulation, seven rank intermodulation etc. all can interfere with other communication system.
[summary of the invention]
The technical problems to be solved in the utility model provides a kind of resonance post that is used for low intermodulation mixer.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of low intermodulation mixer resonance post, comprise resonance post body, resonance post body comprises cylinder, loading disc and step, have installing hole on the step below the resonance post body, it is characterized in that, all there is the obtuse angle all edges and corners of described cylinder, loading disc and step.
Further be that the installing hole on the described step is the smooth through hole of hole wall surface.
The beneficial effects of the utility model are that with the mixer that this resonance post is made, its intermodulation value is extremely low.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the cross-sectional view of the low intermodulation mixer resonance post embodiment of the utility model.
Fig. 2 is the vertical view of the low intermodulation mixer resonance post embodiment of the utility model.
Among the figure, 1-loading disc, 2-cylinder, 3-step, 4-installing hole.
[embodiment]
Fig. 1 is a kind of low intermodulation mixer resonance post, comprises resonance post body, and resonance post body comprises cylinder 2, loading disc 1 and step 3, has installing hole 4 on the step below the resonance post body.
All there is the obtuse angle all edges and corners in loading disc 1, cylinder 2 and the step 3.
The equal abate of all acute angles angle of the resonance post 2 in the cavity 1, step 3 and inside cavity.
Installing hole 4 not tapping on the resonance pylon rank 3.
Fig. 1 is a kind of low intermodulation mixer resonance post, comprises resonance post body, and resonance post body comprises cylinder 2, loading disc 1 and step 3, and cylinder 2, loading disc 1 and step 3 are structure as a whole.Have installing hole 4 on the step below the resonance post body, installing hole 4 is the smooth through hole of hole wall surface.All there is the obtuse angle all edges and corners at cylinder 2, loading disc 1 and step 3.
