Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

In today’s world, power amplifiers are used in many devices for a wide variety of applications. In general, an amplifier takes a low power input and regenerates the signal at several watts higher.

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

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 ...
