The 800-mW NESG250134 and 1W NESG260234 medium-power SiGe (silicon-germanium) HBT (heterojunction-bipolar-transistor) amplifiers suit use in two-way radio applications, such as FRS (Family Radio ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

Until now we have been speaking about the linear distortions of the amplifiers. A linear distortion involves a change in the waveshape, or the frequency response, but where no new frequencies are ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...
