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 ...

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 ...

JFETs are, almost invariably, depletion mode devices, which means that there will be some drain current at a zero-applied gate-source potential. This current will decrease in a fairly linear manner as ...

Understand the basic audio components of a Hi-Fi stereo system so you know what to look for when shopping for audiophile equipment. Amplifier. Amp. Preamp. Integrated amp. Phono stage. Tube amplifier.

As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...

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 ...

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 ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.
