Let’s take an amplifier and feed it with two test signals of identical amplitude, but of two different frequencies which we will call “f1” and “f2”. Since the amplifier is non-ideal, there will be ...

O. Shimbo, and W. L. Cook, in the COMSAT Technical Review. 3 Shimbo et al. provide a computational method to estimate the undesired interference caused by intermodulation products of angle-modulated ...

$3,500 is a lot of money for a hybrid digital power amplifier. The NAD M23 is not your typical hybrid digital power amplifier. Not a chance. I’m must confess to being very ambivalent about “hybrid ...

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.

Zero-drift amplifiers dynamically correct their offset voltage and reshape noise density. Two commonly used types—auto-zero amplifiers and choppers—achieve nanovolt-level offsets and extremely low ...
