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 ...

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 RF testing, an essential attribute of every RF signal generator is the maximum output power it can supply to a device under test (DUT) while maintaining spectral purity and level accuracy. The ...

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 ...

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

It’s no surprise then that one of the first specifications a novice or seasoned enthusiast looking to buy an AV receiver or amplifier sees is its power output ratings. After all, it’s among the most ...
