Abstract

The paraunitary property of lossless networks has been exploited to determine relationships for the scattering parameters of 3-port networks (filter pairs) to predispose approximate Chebyshev or elliptic frequency response characteristics. Prior work by Belevitch, Zhu and Chen determined the relationships for Butterworth frequency response characteristics. Networks which demonstrate approximations to Chebyshev and elliptic response characteristics were synthesized from the reflection coefficient of the network using the Darlington method for the second- and third-order cases. Filter pairs which have perfect, non-approximate Chebyshev or elliptic response characteristics were shown not to exist.
