FIELD: electrical engineering.
SUBSTANCE: invention can be used for antenna-feeder devices. Substance of the invention consists in the fact that the matching balancing device consists of two identical transformers having two windings each, located in the metal housing, filled with cooling liquid, according to invention transformers are made on ferrite annular cores of two standard sizes, located in each other but spaced apart.
EFFECT: technical result is possibility of increase of rated power input, while maintaining mass-dimensional characteristics and electrical parameters.
