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.

Class A devices feature a design in which the output stage passes current at all times, even when the input stage is idle. Class B devices do not pass current when the output device is idle. Class AB ...

Wireless Telecom Group's Boonton unit has launched AmplifierTest Bench, a new software package that simplifies the analysis, test, andcertification of pulsed and linear amplifiers. Furthermore, it ...

Power amplifiers deliver a specific amount of AC power to a load. They are used in audio frequency and radio frequency applications. An RF power amplifier is used to amplify radio frequency (RF) ...

Class-D audio amplifiers, also known as switching amplifiers, achieve high power efficiency by operating their output transistors as rapid on/off switches. An input audio waveform is converted into a ...
