Tables of element values for capacitively coupled double-tuned networks

Abstract

Tables of element values are developed for capacitively coupled double-tuned interstage networks with finite source and load resistances and equiripple insertion-loss characteristics corresponding to minimum passband return losses of 10, 15, 20, 25 and 30dB. In each case the lower edge of the passband is varied from 0.1 to 0.95 by increments of 0.05 with the upper edge normalised to unity. The insertion-loss method of design is used for evaluating the network elements.
