This project was a sort of challenge: designing an audio amplifier capable of delivering a decent output power with a minimum parts count, without sacrificing quality. The Power Amplifier section ...

Peachtree Audio’s GaN400 stereo power amp ($3,000) blazes new trails for Class D amplification. The amp uses cutting-edge GaNFET transistors in its output stage, delivering a massive 400wpc! Read on.

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

Emerging as the industry's highest voltage bipolar transistors designed for audio amplifier output stages, the MJL4281A (NPN) and MJL4302A (PNP) 15A, 230W power transistors specify a sustained ...

This 2 channels audio mixer is based on the 2n3904 transistors which forms 2 pre-amplifiers. The first preamplifier of the audio mixer has a high gain and can be used for microphone input, and the ...

The first step in designing a microwave frequency power amplifier monolithic microwave integrated circuit on a given GaN foundry process is to select the transistor size and bias, writes Liam Devlin.

The 2SA1943N and 2SC5200N transistors are in effective smaller versions the the existing 2SA1943 and 2SC5200 devices in a TO-3P(N) package instead of the previous TO-3P(L) package. The supplier claims ...
