Microwave and millimeter-wave high power vacuum electron devices (VED) represent a modern technological continuation of one of the original and basic building blocks of RF electronics technology. Based on original vacuum tube principles that date from the turn of the 19th to 20th centuries, these present-day incarnations couple modern design and manufacturing techniques to produce reliable high-performance RF power devices. "Vacuum electron devices may at first seem anachronistic," says ABI Research director Lance Wilson. "But in some cases, there is no other way to generate such levels of RF power within an acceptably small space. Certain klystrons and gyrotrons can generate megawatts, and it would take tens of thousands of transistors to do that."
