On the optimum biasing and input out-of-band terminations of linear and power efficient class-AB bipolar RF amplifiers

Optimum bias conditions and out-of-band terminations for bipolar devices are investigated in order to rend the best compromise in linearity, efficiency and bandwidth for class-AB power amplifiers. The optimum collector current and baseband impedance for linearity prove to be fixed for a given bipolar technology and device size.
