Computer aided double matching via parametric representation of Brune functions

A novel method of broadbanding which utilizes the parametric representation of Brune functions is applied to double-matching problems. Examples are presented to exhibit the use of the parametric-broadband matching procedure. The results obtained are compared with those obtained by the real frequency-direct computational technique. It is concluded that the real frequency-direct computational and the parametric methods of broadband matching yield similar results with the same complexity of the matching networks. On the other hand, if the complexity of the equalizer is increased, the parametric approach offers high numerical stability with less computation
