Analysis and Design of Microwave Linearized Amplifiers Using Active Feedback
EDUARDO BALLESTEROS,FELIX PEREZ, AND JORGE PEREZ
Abshurei-Intemodulalion distortion of active feedback amplifier systems has been analyzed using a simple " d . Starting from the amplitude churteristic of both amplifiers-the main and the auxiliary-it is possible t o calculate the i n t e r n " * n distortionof the complete system. Analytical results show that third-orderintermohlation products can be considerably reduced when an active feedback with correct amplitude and phase is employed. Experimental measurements have been made on a one-stage bipolar transistor amplifier that confii the theoretical analysis.
