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.

The FFT from the amplifier output is nice and clean with 2 nd harmonic down -109dB below the fundamental when driven with 2Vrms on the analog inputs. Curious when the same test was repeated with a ...

In today’s information-driven society, there’s an ever-increasing preference to measure phenomena such as temperature, pressure, light, force, voltage and current. These measurements can be used in a ...

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 ...
