Abstract

The considered power amplifier is presented in the form of pre-exit and output stages. The parameters of transistors and the calculation of amplifier modes are described. To build a power amplifier, the use of a pre-exit stage constructed according to a single-ended scheme and an output stage built according to Dogerty’s circuit is used. By selecting transistors with different parameters on the basis of calculations, you can build amplifiers of various power with high quality characteristics and high efficiency.

Keуwords: amplifier; pre-cascade circuit; output stage circuit; efflciency; amplifier modes.
