Power amplifiers (PAs) for RF/microwave use come in various shapes and sizes, at many different performance levels, and based on numerous technologies. Differences in capabilities separate one PA from another as a better fit for a particular system. But one key difference perhaps stands apart from the rest: Has the PA been designed for continuous-wave (CW) or pulsed amplification, such as in communications or radar systems, respectively. Furthermore, what characteristics can help make an amplifier a good fit for either a CW or pulsed application?...
