Abstract
Tables of normalized lumped lossless two-section impedance matching networks, which closely approximate -4, -5, and -6 dB per octave attenuation versus frequency characteristics are provided. Impedance transformation ratios vary from 20:1 to 100:1. Bandwidths range from 30 to 67 percent. The networks are particularly suited to broad-banding of RF power transistor stages. Measured performance of a 12-W, 225-400-MHz transistor stage illustrates application of the designs.
