APPARATUS AND METHOD OF TUNING MICROWAVE FILTER |
摘要 |
Disclosed are an apparatus and a method of tuning a microwave filter. An apparatus for tuning a microwave filter according to the present invention includes: a measurement device configured to measure a scattering (S) parameter curve of a microwave filter desired to be tuned; a control device configured to perform tuning so that a shape of the S parameter curve according to a movement of a preselected tuning screw is matched to a shape of a target S parameter curve, and then determine a quantity of transfer of the tuning screw based on feature points on the S parameter curve by using a least squares method in which a preset weight is reflected; and a tuning device configured to move the tuning screw based on the determined quantity of transfer of the tuning screw.
