FILTER COMPONENT TUNING METHOD

Target mode frequencies are calculated for a defined filter component used as a reference for filter components to be tuned. The defined filter component has resonant mode(s), each having a mode frequency which can be tuned to a corresponding target mode frequency via physical adjustment of parameter(s) of the filter component. A tuning equation is formed by linearly relating, via a slope matrix, changes in the mode frequencies to corresponding physical adjustment in the parameter(s), and by using an inverse of the slope matrix as part of the tuning equation. A tuning procedure is performed for a filter component to be tuned, comprising: determining, using the tuning equation, adjustment information for parameter(s) of the filter component to adjust measured mode frequency(ies) of the filter component toward meeting corresponding target mode frequency(ies) for the resonant mode(s) within corresponding tolerance(s); and outputting the determined adjustment information for physical adjustment of the parameter(s).
