FIELD: electricity.
SUBSTANCE: unit of a microwave generator comprises units (2a, 2b) of generators, units (3a, 3b) of power dividers, units (5a-5d) of power amplifiers, a heating chamber (10), comprising an object to be heated, and multiple units (8a-8d, 9a-9d) of supply, which are arranged on the surface of the heating chamber wall, in order to supply microwaves to the chamber, in which the difference of phases and frequency of generation produced from supply units controlled as a pair are controlled in turns.
EFFECT: improved heat efficiency by reduction of reflected capacity.
