SOLID-STATE POWER AMPLIFIER Russian patent published in 2011 - IPC H03F3/00 

FIELD: electricity.

SUBSTANCE: device includes preliminary amplifier 1 the input of which is amplifier input, and output is connected to input of divider 2 of power 1/N, the outputs of which are connected through modules 7 of phase correction to inputs N of amplifiers 3 of the channel. Outputs of amplifiers 3 of the channel are connected through coaxial-waveguide transitions 11 to inputs of adder 4 of power N/1, to the outlet flange of which there connected through directed brancher 12 is detector head 8. Output of detector head 8 and input of module 5 of address disconnection of the channel amplifiers (ADCA) is connected to bi-directional external control bus 10. Output of module 5 of ADCA is connected to control input of module 6 of distribution of modulating pulses, N outputs of which are connected to control inputs N of amplifiers 3 of the channel, N+1 output is connected to control input of preliminary amplifier 1, and signal input is connected to input bus 9 of modulating pulse.

EFFECT: reducing the range of change of efficiency coefficient of amplifier and maintaining the setting of amplifier at adjustment of its output power within considerable limits.
