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 industry briefing George Bollendorf explains a new approach that matches input pulse signal shape, minimizes droop, overshoot, ringing, rise and fall times.
Pulse shaping is a leap ahead technology that we are perfecting for implementation into our existing high power amplifier architecture. This next feature set for our multimode interoperable SSPA’s has particular significance for electronic warfare applications. No other amplifier manufacturer in the Western world has this capability and so I thought you would be interested to learn of our progress given its relevance.
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.
