The design objectives for a 10 watt X-Band VTM are discussed and the prior art is reviewed. The general approach is evolved from considerations of the problem of mode stability and coupling. Two basic designs are presented, one interdigital and one consisting of a novel approach with the cavities integral to the vacuum device. Detailed information on the theory of each of the basic designs is given as well as information on the fabrication of the units. Circuit configurations are discussed and a suitable circuit for each of the designs is evolved. A chronological review of all results of operating tubes is given with discussions of important design changes and the reasons for them. Units were developed which exceeded the objective specifications, the most significant performance being 14 watts at 33 efficiency over the 7.0 to 8.0 Gc band. The principal problem area, a lack of consistency in results obtained, is discussed in detail. The composite results are analyzed in terms of the objectives and recommendations are made for further development.
