Existing synthesis techniques are utilised to develop Tables of low-pass prototype element ‘g’ values of predistorted singly and doubly terminated first-kind 0.01 dB-ripple Cheby̅shev-filter networks with up to nine sections. Through conventional frequency-transformation techniques, corresponding bandpass circuits can also be realised. Excessive predistortion (low Q factor) will deteriorate the passband voltage standing-wave ratio, whereas the effects on stopband selectivity are insignificant. Further, the sensitivity of the prototype-element values becomes more acute as the requirement for predistortion is increased. The Tables may be used as a design tool for realising the optimum prescribed insertion-loss characteristics in practical microwave networks where the effects of parasitic component dissipation are critical.
