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 series discussed the need to verify SPICE model accuracy and how to measure the output impedance and small-signal bandwidth of operational amplifier (op amp) models. In ...

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 ...

Teseq has expanded its broadband amplifier line to include a Class A linear and low distortion model that operates from 10 kHz to 400 MHz with a rated power level of 260 watts. Teseq has expanded its ...
