Klystrons, Traveling Wave Tubes, Magnetrons, Crossed-Field Amplifiers, and Gyrotrons

摘要

Microwave Vacuum Tubes come in many shapes, sizes, and output-power ratings. As detailed in Klystrons, Traveling Wave Tubes, Magnetrons, Crossed-Field Amplifiers, and Gyrotrons by A.S. Gilmour, Jr., the technologies behind these devices are quite mature, largely dating to the time of and before World War II. Although they are mature, microwave vacuum tubes have proven their reliability. For that reason, they are often employed in deep-space applications including in satellite communications (satcom) systems. Microwave vacuum tubes are also quite efficient in turning bias energy into high-frequency output power—much more so than their solid-state counterparts.
