BROADBAND POWER AMPLIFIER Russian patent published in 2014 - IPC H03F3/00 

FIELD: radio engineering, communication.

SUBSTANCE: broadband power amplifier comprises a non-inverting output stage (1), the input of which is connected to the input of the device (2) and an input voltage source (3) through a matching resistor (4), a load circuit (5) connected to the output (6) of the device, connected to the output of the non-inverting output stage (1). The circuit includes a correcting stage (7), the current output (8) of which is connected to the input of the non-inverting output stage (1); a first (10) additional resistor is connected between the input of the device (2) and the input (9) of the correcting stage (7), and the output of the device (6) is connected to the input (9) of the correcting stage (7) through series-connected additional inverting buffer amplifier (11) and second (12) additional resistor.

EFFECT: low level of nonlinear distortions and different types of noise in the load circuit of the broadband power amplifier with a non-inverting output stage.
