24 September 1987 Radio-Frequency (RF) Vacuum Electronics: A Resurgent Technology For Tomorrow
Author Affiliations +
Recent advances in the development of fast-wave, or periodic-beam, devices operating at millimeter- and submillimeter-wavelengths are not the only signs of resurgence in the field of RF vacuum electronics. Significant progress is being achieved in areas of well-established slow-wave power tube technology. In addition, the field is being stimulated by the introduction of techniques (CADD/CAM and microelectronics fabrication) and technologies (improved magnetics) from other disciplines. By any single-parameter measure -- peak or average power, efficiency, bandwidth noise reduction -- or by more complex figures-of-merit -- power-bandwidth product, Pf2 -- vacuum RF power device performance is advancing, not incrementally, but at "breakthrough" rates. This dramatic progress could presage a period of growth in RF vacuum electronics unequaled since the postwar period of achievement in magnetron and klystron development.
