ABSTRACT:
A broad-band power amplifier circuit having a transistor with a base terminal, an emitter terminal, and a collector terminal connected between a positive power source terminal and a negative power source terminal. A bias circuit is connected to the base terminal of the transistor, a capacitor is connected between the collector and emitter terminals of the transistor, and an inductor is connected between the emitter terminal of the transistor and the negative power source terminal. A decoupling choke is connected between the collector terminal of the transistor and the positive power source terminal, a first decoupling capacitor is connected to the collector terminal of the transistor, and a second decoupling capacitor is connected to the base terminal of the transistor.
