SYSTEM OF ARRAY PHASING-IN (VERSIONS) Russian patent published in 1997 - IPC

FIELD: radio engineering; may be used for construction of HF radio communication centers with capability of coherent summing of powers of several radio transmitters. SUBSTANCE: system of phasing-in of n element array has diagram-forming circuit of quadrature type with n outputs, m inputs and p radio transmitters, commutator which outputs are connected to inputs of diagram-forming circuit and switches and adders distributed in k levels. Output of each radio transmitter is connected to input of corresponding switch of first level, first outputs of switches of all levels are connected directly to inputs of commutator and second outputs, through proper adders to inputs of commutator or to inputs of switches of next level. EFFECT: enhanced efficiency. 2 cl, 4 dwg, 1 tbl
