MONOTRON MICROWAVE GENERATOR WITH MATRIX FIELD EMITTER CATHODE Russian patent published in 2017 - IPC H01J25/20 

FIELD: electronics.

SUBSTANCE: invention relates to electronic equipment, in particular, to miniature electromagnetic oscillations vacuum generators of SHF range short-wave part, for example to monotrons. Monotron microwave generator with matrix field-emission cathode comprises electrons source, single-gap resonator, reflector, insulator, power supply sourses, SHF energy output device. Source of electrons is made in form of group of separate field emission matrices, arranged on common cathode base. In space between second capacitive electrode and reflecting electrode included two-gap resonator with central and third capacitive electrodes, provided with holes for passage of electron flow, arranged coaxially to span holes in single-gap resonator first and second capacitive electrodes. Central capacitive electrode is installed on ceramic substrate, suspended between second and third capacitive electrodes, and connected to two-gap resonator housing by resonator three strip conductors, two of which are located on single-gap resonator second capacitive electrode side and together with the second capacitive electrode forms half-wave resonant circuit, and third strip conductor is on guide on side of two-gap resonator third capacitive electrode and together with said electrode forms quarter-wave resonant circuit. Second capacitive electrode of resonator contains communication holes providing electromagnetic communication between single-gap and two-gap resonators. Single-gap resonator is made with gap by high frequency via locking capacitance, formed between first capacitive electrode side part and resonator housing.

EFFECT: technical result is increase in efficiency and output power.
