However, the multiple switches and multiple filters in the existing L-wave multi-channel switched filter bank are usually set separately, so the structure is complex, the volume is large, it is not easy to produce and assemble, so the use is not flexible enough
At the same time, the existing L-wave multi-channel switching filter bank has high production cost, which is not conducive to the use of small and medium-sized enterprises.

The invention discloses a miniaturized L-wave multi-channel switch filter bank. The filter bank comprises an installation shell and a secondary shell, the bottom of the installation shell is inserted in the secondary shell, a partition board is fixed in the installation shell and divides the inside of the installation shell into an adjusting cavity and an installation cavity, the adjusting cavity is located above the top of the installation cavity, the top of the installation shell is provided with a round hole communicated with the adjusting cavity, an adjusting column is arranged in the round hole, an adjusting knob is fixed on the top of the adjusting column, a spring limiting block is fixed at the bottom of the adjusting column, the outer side of the adjusting column is sleeved with a spring, the spring is fixed on the top of the spring limiting block, and a connection pipe is fixed at the bottom of the spring limiting block. A switch and a filter are integrated, the size is reduced, the structure is simple, operation is convenient, the channel switching speed is high, and the manufacturing cost is low.
Description
technical field [0001] The invention relates to the technical field of filter banks, in particular to a miniaturized L-wave multi-channel switch filter bank. Background technique [0002] In modern mobile communications, frequency-selective networks are widely used in the field of communication, and switching filters are key components in frequency-selective networks. The switching filter has the characteristics of high performance value, high power capacity, and multi-band selection filtering can be realized by switching. [0003] However, the multiple switches and multiple filters in the existing L-wave multi-channel switched filter bank are usually set separately, so the structure is complex, the volume is large, and it is not convenient for production and assembly, so the use is not flexible enough. At the same time, the existing L-wave multi-channel switching filter bank has high production cost, which is not conducive to the use of small and medium-sized enterprises. ...
