Linearity and power efficiency in power amplifiers are critical to the signal quality and battery life of 5G designs. Traditional methods for characterization testing of power amplifiers (PA), however ...

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.

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

Complementing the existing frequency range of 0.8 GHz to 3.0 GHz in power classes up to 200 W, the BBA150 broadband amplifier from Rohde & Schwarz is now available with frequency coverage from 2.5 GHz ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...
