Evolution of multi-octave helix traveling wave tubes
Increasing demands of system integrators and designers, on efficiency and increased capability, have lead to a requirement for higher RF power levels and greater operational bandwidth. This paper describes the design, theoretical modeling and experimental data collated through the development of two multi-octave mini travelling wave tubes (TWTs) during the last 12 months.
