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.

We recently saw how certain audio power amplifiers can be used as oscillators. This Design Idea shows how those same parts can be used for simple amplitude modulation, which is trickier than it might ...

The circuit was designed to produce an audio power amplifier that operates in the range of Class A type while providing a power output of 40 Watts. Class A – refers to an output stage where the bias ...

Don’t get zapped when buying a new high-voltage DC power supply. Understand the specifications first. Lasers, linear accelera-tors, X-ray machines, defibrillators, radar, and numerous other ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...
