Abstract
A filter includes a case, a number of resonant columns received in the case, a partition walls received in the case and located between the adjacent resonant columns, a number of blend strips fastened on the partition walls, and a cover covering on the case. The cover defines a number of regulating through hole corresponding to the resonant columns and the blend strips and includes a number of regulating bolts passing through the regulating through hole to couple with the resonant columns and the blend strips. The regulating bolts move upwards and downwards in the regulating through holes to regulate a transmission zero of the filter.
Claims14
A blend strip used in a filter to transmit electrical signal, comprising:
- a main body comprising an upper part, a lower part bent downwards relative to the upper part, and a pair of wings corresponding extending from two opposite sides of the lower part;
- and
- a pair of arms correspondingly extending from two opposite ends of the main body towards a same direction;
- wherein the lower part is located at a center of the main body, and the wings extend along a direction perpendicular to a plane defined by the main body and the arms.
A filter, comprising:
- a case;
- a plurality of resonant columns received in the case, wherein the resonant columns are divided into at least two groups and the resonant columns of the same group are lined along a same direction;
- a plurality of partition walls received in the case and located between the adjacent resonant columns of the same group;
- a plurality of blend strips fastened on the partition walls;
- and
- a cover covering on the base;
- wherein the case comprises a signal input port connected to one of the resonant columns or a signal output port connected to the other resonant columns, signal is input to the case via the signal input port and is transmitted to the output port via a first path alternatively passing through the resonant columns of different groups and a second path passing through the blend strips and the resonant columns.
