AMPLIFICATEUR DE PUISSANCE AVEC CIRCUIT DE POLARISATION INTÉGRÉ DOTÉ D'UNE ENTRÉE MULTIPOINTS

摘要

A power amplifier includes a semiconductor die, and an amplifier and bias circuit integrally formed with the semiconductor die. The die has opposed first and second sides, and a device bisection line extends between the first and second sides. The bias circuit includes a multi-point input terminal with first and second terminals that are electrically connected through a conductive path that extends across the device bisection line, and one or more bias circuit components connected between the multi-point input terminal and the amplifier. The amplifier may include a field effect transistor (FET) with gate and drain terminals, and the bias circuit component(s) are electrically connected between the multi-point input terminal and the gate terminal. In addition or alternatively, the bias circuit component(s) are electrically connected between a multi-point input terminal and the drain terminal. The one or more components may include a resistor-divider circuit.
