Abstract:
1. A method, comprising: providing a filter including at least one resonator(s) and at least one tuning element(s), said filter having one or more filter design parameters selected from a group that includes resonator frequencies and resonator to resonator coupling values; measuring a response of said filter so as to generate a set of measured data; analyzing the set of measured data to extract one or more filter design parameter(s) to optimize; optimizing a selected subset of filter design parameters to achieve a desired filter response; generating a tuning recipe for an operator or automated tuning system to use in tuning the filter; and tuning the filter by altering the tuning elements as established by the tuning recipe so as to correspond to said subset of filter design parameters, wherein the filter response measurement is carried out at a standard operating temperature of the filter and the tuning of the tuning element(s) is carried out at a temperature that is not an expected operating temperature of the filter.
