Abstract: This paper investigates two novel triple-transistor Doherty power amplifier (DPA) designs. A compact fully differential DPA topology will be firstly introduced. Three active devices, two ...

The SERENADE Wireless amp circuit is based on a Class A design, supplemented by a precisely matched, discrete transistor amplifier circuit, with dozens of power transistors that are precisely matched, ...

Dive into the incredible restoration of a 16-transistor amplifier as each part is carefully checked, cleaned, and restored to perfection. This project includes washing and repairing every ...

In order to develop the necessary technology, the project Magellan — High Efficiency mm-Wave GaN Transistor High Power Amplifier for GEO and LEO Active Antenna Application — was launched in 2024.

This note describes a method of applying current negative feedback to transformerless audio class-AB transistor stages. The output impedance of the circuit is very high but the circuit may also be ...

By contrast, an analog amplifier that weighs less may use a smaller transformer with inadequate capacity and fewer or thinner heat sinks (heat sinks look like radiator fins and are used to dissipate ...

musicians and listeners for their sonic charms—ample enough to cause some to forswear the transistor amp forever. “The difference between tubes and transistors is like the difference between ...
