SHF generator having one double-gap resonator which works in the mode of in-phase oscillation with monotrone effect in the first interaction space has been considered. This interaction space is extended and has the transit angle more than 2,4π. It serves as an efficient electron buncher, which enables to receive the relative amplitude of convection current of first harmonic more than 1,5. Supplementary factor of device efficiency increase is the energy removed from the electron flow due to the monotrone effect in this interaction space. Conditions of efficient operating support have been discussed. A method to receive appropriate gap voltage amplitude ratio under high resonator characteristic impedance has been proposed. Numerical computations and analysis of electronic processes have been carried out, and availability of power efficiency coefficient about 55 % has been shown.
Key words: generator, double-gap resonator, in-phase oscillation mode, monotrone effect, extended interaction space, large voltage amplitude, efficiency coefficient.
