Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

This audio amplifier circuit delivers up to 200 W of top-class quality for loudspeaker from 4 to 16 ohm. Operating voltage is between 24 and 36 V, max 5 A. The frequency response is from 20 to 20000 ...

The performance of Hetero junction bipolar transistors made up of compound semiconductor material are prone to variations in temperature, which create distortion in the circuit made out of such ...

Researchers at Fraunhofer IAF have developed a GaN transistor technology with a gate length of 70 nm that achieves record ...

It may seem like a holdout against the solid-state world, but the vacuum-tube magnetron is still at the heart of every consumer microwave oven and many commercial ones used for cooking or drying.

SweGaN is providing epitaxial wafers for the collaboration, which will explore the material properties and the ...
