Abstract: The first vacuum tube amplifiers appeared circa 1912 and were used originally as audio amplifiers. Shortly thereafter they helped to popularize AM radio broadcasting. Generating sufficient broadcast power was difficult and electricity costs were high for operators, driving many key innovations to improve output power and efficiency, particularly when amplifying signals with large peak-to-average power […]

But here’s the catch: a successful research career isn’t just about the best experiments or the most cited papers. It’s also about navigating the human side of […]
