Abstract :
A filter prototype for increasing the tolerance of passive networks to load variations is presented. A method based on the way in which a network´s reflection coefficient changes in response to component and load reactance variations is used to develop the filter polynomial. This filter polynomial has greater tolerance to load reactance variations, component variations, and finite-element Q than Butterworth, Chebyshev, or elliptic structures. Examples using this filter for tolerance enhancement of filters and matching structures are presented
