Description
Technical field
The utility model relates to a kind of bank of filters, particularly a kind of Hexamermis spp switch filter group.
Background technology
In present mobile communication, frequency-selective network is widely used in the communications field, and switch filter is the critical component in frequency-selective network.Switch filter is had performance values, high power capacity and just can be realized the characteristic of multiband Choose filtering by switching over, but the filter usually in switch filter group adopts screw fixation method to fix usually, so just must leave the fixed space of screw for, cause volume comparatively large, and be not easy to produce and assembling.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Hexamermis spp switch filter group, and this bank of filters volume is little, and processing technology is simple, and tuning space is high.
For achieving the above object, the utility model provides following technical scheme: a kind of Hexamermis spp switch filter group, comprise base plate, the middle body of described base plate is provided with groove, by the gluing note bank of filters of conduction in groove, and two of groove sides install input radio frequency switch respectively, export radio-frequency (RF) switch, base plate and input radio frequency switch, the side exporting radio-frequency (RF) switch corresponding installs input radio frequency contact pin respectively, export radio frequency contact pin, described input radio frequency switch, export radio-frequency (RF) switch to be all connected with each filter in bank of filters respectively by wire, and described groove is at input radio frequency switch, export the through hole that radio-frequency (RF) switch place all offers through-going recess wall, in through hole, equal button installation is installed, the part that two buttons are positioned at groove respectively with input radio frequency switch, output radio-frequency (RF) switch connects, the top of described base plate is provided with switch control rule port, switch control rule port and input radio frequency switch, export radio-frequency (RF) switch to be connected by wire, each filter in described bank of filters all comprises three relatively independent and resonant cavitys of cascade, and the height of each resonant cavity is 1/8 wavelength, described base plate establishes reeded surface to pass through cover plate for sealing.
Preferably, input radio frequency contact pin, output radio frequency contact pin are connected with base plate by spot welding mode.
Adopt technique scheme, the mode of the gluing note of conduction bank of filters is adopted to be fixed in the groove of base plate, and each filter in bank of filters comprises three separate and resonant cavitys of cascade, and by the limitation in height of each resonant cavity to 1/8 wavelength, the performance values of bank of filters, the characteristic of high power capacity is maintained while reducing bank of filters volume, the utility model reduces the volume of Hexamermis spp switch filter group entirety, is convenient to produce and assembling.
