High power amplifiers do a poor job duplicating the input signal without distortions. Due to the transient response of the amplifier the output will over shoot, ring and droop, introducing undesired low and high frequency components into other parts of the spectrum. Pulse shaping, as it is done today, is an effort to fix fidelity issues caused by the transmitting amplifier and is accomplished by a combination of imperfect methods, most external to the amplifier. In this technical presentation Paulo Correa explains a new approach that matches input pulse signal shape, minimizes droop, overshoot, ringing, rise and fall times.
