Abstract
The utility model discloses multiband switch filtering assembly, comprise low pass filter, the first hilted broadsword ten throw switch and the second hilted broadsword ten throw switch; The filter of ten frequency ranges is provided with between described first hilted broadsword ten throw switch and described second hilted broadsword ten throw switch; Described low pass filter is connected with described first hilted broadsword ten throw switch; Described first hilted broadsword ten throw switch and described second hilted broadsword ten throw switch inside are provided with biasing circuit.The filter of ten frequency ranges arranged between one hilted broadsword ten throw switch and the second hilted broadsword ten throw switch can be selected according to the demand of user, the bandwidth of multiband switch filtering assembly is obtained and significantly improves.
Description
Technical field
The utility model relates to filter; Be specifically related to a kind of multiband switch filtering assembly.
Background technology
Filter is that a kind of being used for reduces or eliminates the electric component of harmonic wave to effect on power system, obtains pure direct current by inputing or outputing through filtration.The filter of current commercial type, its bandwidth is 30% usually, exceedes this bandwidth filter and just not easily makes.When the frequency range of multiband switch is more than 20MHz, its Insertion Loss will increase 1-2dB, so just the difficult Insertion Loss index reaching user.
Utility model content
For above-mentioned deficiency of the prior art, the bandwidth of the multiband switch filtering assembly that the utility model provides obtains and significantly improves.
In order to reach foregoing invention object, the technical solution adopted in the utility model is: provide a kind of multiband switch filtering assembly, and it comprises low pass filter, the first hilted broadsword ten throw switch and the second hilted broadsword ten throw switch; The filter of ten frequency ranges is provided with between described first hilted broadsword ten throw switch and described second hilted broadsword ten throw switch; Described low pass filter is connected with described first hilted broadsword ten throw switch; Described first hilted broadsword ten throw switch and described second hilted broadsword ten throw switch inside are provided with biasing circuit.
During design, preferred described biasing circuit forms primarily of taper inductance.
During design, preferred described taper inductance adopts the enamelled wire coiling of diameter 0.06mm to form.
During design, preferably the filter of ten frequency ranges is respectively 20-90MH filter, 80-150MH filter, 140-270MH filter, 260-510MH filter, 2590-3000 MH filter, 2240-2600 MH filter, 1890-2250 MH filter, 1540-1900 MH filter, 970-1550 MH filter and 500-980 MH filter further.
During design, the operating frequency of further preferred described multiband switch filtering assembly is 20 ~ 3000MHz.
During design, then the working temperature of further preferred described multiband switch filtering assembly is-45 DEG C ~ 70 DEG C.
During design, further preferred described multiband switch filtering assembly is of a size of 102mm × 85mm × 12mm.
The beneficial effects of the utility model are: the filter of ten frequency ranges arranged between the first hilted broadsword ten throw switch and the second hilted broadsword ten throw switch can be selected according to the demand of user, the bandwidth of multiband switch filtering assembly is obtained and significantly improves.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model multiband switch filtering assembly embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
With reference to the theory diagram that figure 1, Fig. 1 is the utility model multiband switch filtering assembly embodiment, the technical scheme of this embodiment is:
Comprise low pass filter, the first hilted broadsword ten throw switch and the second hilted broadsword ten throw switch; The filter of ten frequency ranges is provided with between first hilted broadsword ten throw switch and the second hilted broadsword ten throw switch; Described first hilted broadsword ten throw switch and described second hilted broadsword ten throw switch inside are provided with biasing circuit.After the arranging of the filter of ten frequency ranges, user can select according to its demand the frequency range that needs, the bandwidth of multiband switch filtering assembly is obtained and significantly improves.
Because the suppression of the side frequency place filter at 4000-6000MHz can upwarp, arrange low pass filter can avoid occurring this situation, the position that the circuit of multiband switch filtering assembly arranges low pass filter should be considered to be placed on the forward and backward of offset line, even if offset line has leakage like this, also can filter, so low pass filter is connected with the first hilted broadsword ten throw switch.
When the frequency of multiband switch filtering assembly reaches 3000MHz, the Insertion Loss of multiband switch filtering assembly will increase by 1 dB-2dB, so just can not reach the Insertion Loss index of user.So in an embodiment of the present utility model, biasing circuit forms primarily of taper inductance.
In order to reduce the stray capacitance of biasing circuit, widening frequency band, in an embodiment of the present utility model, taper inductance adopts the enamelled wire coiling of diameter 0.06mm to form.
In an embodiment of the present utility model, the filter of ten frequency ranges is respectively 20-90MH filter, 80-150MH filter, 140-270MH filter, 260-510MH filter, 2590-3000 MH filter, 2240-2600 MH filter, 1890-2250 MH filter, 1540-1900 MH filter, 970-1550 MH filter and 500-980 MH filter.
In an embodiment of the present utility model, have good serviceability in order to ensure multiband switch filtering assembly, the operating frequency of multiband switch filtering assembly is 20 ~ 3000MHz; The working temperature of multiband switch filtering assembly is-45 DEG C ~ 70 DEG C.
In an embodiment of the present utility model, multiband switch filtering assembly is of a size of 102mm × 85mm × 12mm.
Although describe in detail embodiment of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection range to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection range of this patent.
