Compensation of the phase flicker noise in a bipolar-transistor power amplifier

Relationships between the parameters of a bipolar-transistor (BT) common-base power amplifier, which provide compensation of the flicker component of the phase noise of the output signal during operation in the linear mode, are obtained. This effect is revealed in the microwave frequency band by means of numerical simulation. It is shown that after introduction of nonlinear parameters in the BT equivalent circuit, the effect persists in some vicinity of the compensation point calculated for the linear case.
