Abstract
This invention relates to a method for determining element values of a filter structure having a linear sequence of coupled resonators, wherein a coupling between adjacent resonators is determined by one or more coupling factors, the method comprising deriving an input-to- output transfer function on the basis of an Impedance or Admittance matrix, wherein the matrix is determined as a function of input resistance, output resistance, resonator detuning and as a function of coupling factors, representing one of Kirchhoff's laws for loops or nodes of the filter structure and including the coupling factors; determining one or more conditions for the coupling factors such that the input-to-output transfer function; determining the coupling factors using the one or more determined conditions; and deriving element values of the filter structure in dependence on the determined coupling factors.
