MULTISTAGE DEVICE FOR SUMMATION OF SHF-AMPLIFIERS POWER Russian patent published in 2008 - IPC H03F3/189 H03F3/60 

FIELD: physics, radio.

SUBSTANCE: invention is related to SHF radio engineering and may be used in development of radio transmitting devices for up-to-date radio engineering communication systems, radiolocation, radio navigation. Multistage device for summation of SHF amplifiers power consists of n serially connected cascades of amplification, where n=1, 2, 3, etc. Every cascade of amplification contains N-channel divider of power, N-channel summator of power and N of SHF amplifiers, where N=2^m. In every cascade of amplification, apart from outlet cascade, to one outlet in every pair of outlets of N-channel power divider phase changer is connected, which is arranged as 120-degree at decreasing dependence of output power of SHF-amplifiers with growth of frequency, or as 240-degree - at increasing dependence of output power of SHF-amplifiers with frequency growth.

EFFECT: higher efficiency factor, provision of summary power stabilisation, if one or several SHF amplifiers fail, possibility of frequency correction of summary power level, reduction of weight and dimensions, higher reliability of device operation.
