hello everybody
i want design coaxial bandpass filter and the resonator is disk in coaxial cable. i use chebyshev method for design in matthaei book(ch8, p.432), and i use impedance inverter, i want calculatre reactance of disk (X), for solve reactance slope parameter(x). this parameter is defined in this book. but i can't how to calculate X parameter. please give me help.
e.g. 3 pole chebyshev: X1=X4, X2=X3 , x=w0/2*dXi/dw (w0=center freq.)
thanks and regard
