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 naming is based on Mercury being the closest planet to the sun, while Solis is Latin for sun: the power amplifier as the energy source, the pre-amplifier as its nearest companion.

The literature on power amplifiers frequently discusses the importance of power-supply rejection in audio amplifiers, particularly in reference to its possible effects on distortion [4]! I have (I ...
