Let's assign a point system to determine if you may benefit from an external amplifier, or if you would be better served by saving your cash. Please keep in mind this is not a biblical source. I ...

The voltage-amplifier stage (or VAS) has often been regarded as the most critical part of a power-amplifier, since it not only provides all the voltage gain but also must deliver the full output ...

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 ...

This article was originally fairly superficial and frivolous, but has been expanded (a little) to explain the matter better. Amplifier power ratings are usually honest in Hi-Fi equipment, but become ...

Specifying the power supply requirements for audio amplifiers can be tricky. If the power supply is overdesigned it will add unnecessary cost to the product, and if it supply is underdesigned the ...

The need for high power in the VHF, UHF, and microwave bands has led to transistors that can easily supply tens to hundreds of watts at RF frequencies to 10 GHz and beyond. Most of these devices are ...

Over the years, tutorials have appeared in EMC journals explaining how to estimate the power required from a power amplifier intended for use in an RF immunity test system. Little material, if any, ...
