摘要
A new technique for predistorting filter transfer functions to compensate for the dissipative losses present in the resonator elements is introduced. The method is based on the formation of two admittances from lossless transfer functions. Each admittance is then individually predistorted and connected to a 3-dB hybrid coupler. A simulated numerical example demonstrates that the method is capable of designing network prototypes with a combined predistorted reflection and transmission functions. Tables of prototype element values for elliptic lowpass/highpass functions are also provided. Copyright (C) 2001 John Wiley & Sons, Ltd.
