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.

In a world of tight timelines and ever-increasing performance requirements, it’s critical to create circuit designs right the first time; thus, engineers in the analog and mixed-signal industry often ...

Previous installments of this article series discussed the need to verify SPICE model accuracy and how to measure the output impedance, small-signal bandwidth, and input-referred errors of operational ...

There has been a lot of controversy on many of the Internet forums regarding power capability of receivers when driving multi-channel speaker systems. Some argue that when a receiver is rated at ...

More often than not we see folks on our forums and other forum websites debating how powerful a particular amplifier or receiver is based upon a single test popularized by many print magazines and ...

The third edition of IEC 61000-4-3, published in 2006, has mandated changes in some key areas that may require the replacement of your radiated immunity test amplifier. Along with extending the test ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...

I'm researching preamp-amp matches and due to lack of information on the Internet am left with a question regarding output/input differences between balanced and unbalanced feeds. The contemplated ...
