Abstract
A variety of circuits, methods and devices are implemented for radiofrequency amplifiers. According to one such implementation, a radiofrequency amplifier circuit is implemented in a SMD package. The circuit amplifies a radiofrequency signal having a base-band portion and a plurality of carrier signals frequency-spaced larger than the base-band bandwidth. The circuit includes a radiofrequency transistor connected to a circuit output having a parasitic output capacitance. The source-drain terminal is electrically connected to the circuit output. An internal shunt inductor provides compensation for the parasitic output capacitance. A high-density capacitor is connected between the internal shunt inductor and a circuit ground. The high-density capacitor has a terminal with a surface area can be at least ten times that of a corresponding planar surface.
