Abstract
A method for compensating a temperature drift of a microwave filter comprises: measuring a first frequency response of a microwave filter at a first temperature; determining values of elements of an equivalent circuit corresponding to the microwave filter such that a first modelled frequency response computed using the equivalent circuit matches the first measured frequency response to obtain a first model modelling the microwave filter at the first temperature: measuring a second frequency response of the microwave filter at a second temperature; determining values of elements of the equivalent circuit corresponding to the microwave filter anew such that a second modelled frequency response computed using the equivalent circuit matches the second measured frequency response to obtain a second model modelling the microwave filter at the second temperature; and adjusting an overall temperature drift of the microwave filter to adjust the temperature drifts of the resonant filter elements.
