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.

Howdy guys - I have an XPA-2 amp hooked up to a pair of B&W683's and am curious how many watts (in real time) I am using. I am not worried about over driving the speakers or worried that the amp is ...

Emerging as the industry's highest voltage bipolar transistors designed for audio amplifier output stages, the MJL4281A (NPN) and MJL4302A (PNP) 15A, 230W power transistors specify a sustained ...

The audio analyzer can measure electrical performance only at the output jacks available on the system under test. Therefore, no one can enforce the speaker performance because the speaker is enclosed ...

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 ...

The circuit is all about a power amplifier that can provide a power output of 60 W while operating in Class A mode. Class A – refers to an output stage where the bias current is greater than the ...

Amplifiers are an invaluable tool in this day and age. It’s a way to increase the power of a signal, power that the signal wouldn’t be able to achieve on its own. So, with an amplifier, you can make ...
