DISTRIBUTED-GAIN AMPLIFIER Russian patent published in 2005 - IPC

Abstract RU 2259006 C1

FIELD: radio communications; transmitting devices.

SUBSTANCE: proposed amplifier has N active components 1₁ through 1_N, input transmission line of N + 1 series-connected sections 2₁ through 2_{N + 1}, N + 1 sections 3₁ through 3_{N + 1} of output transmission line, ballast loads 4, 5, N output selector switches 6₁ through 6_N, N power switches 7₁ through 7_N, N active-element inputs 8₁ through 8_N, N power units 9₁ through 9_N, N control switches 10₁ through 10_N, and N resistors 11₁ through 11_N, as well as control unit 12, and logical one shaper 13. Relevant instructions depending on desired output power level are supplied to information inputs of control unit and instruction for turning-on desired active elements is generated.

EFFECT: ability of output voltage regulation without reducing efficiency.
