In the beginning, RF design was a long, slow iterative process, with designers crafting their skills through . J trial and error, gradually developing an intuition of what works by accumulating many failures from what did not work. Successful designers who honed their capabilities were considered gurus, practitioners of both science and magic. Computer-aided design has since transformed RF design, beginning with linear circuit simulation, then evolving to nonlinear simulation and electromagnetic (EM) analysis. Software powered by ever-improving computational hardware has drastically reduced design risk and development time, making the holy grail of first-pass success achievable for many RF, microwave and mmWave designs.
