The klystrode—An unusual transmitting tube with potential for UHF-TV

Economic considerations, especially the increasing cost of energy, have forced electron power tube designers to revise current designs and to re-examine old ones. One result of this re-examination is the rebirth and improvement of a very old and largely forgotten device which appears to hold great promise as a generator of tens to hundreds of kilowatts in the UHF range, with special advantages in TV service. The device itself is described both theoretically and in practical terms, its performance to date and its calculated limits of power output are given, and examples of RF circuitry are shown.
