Load-pull characterization is an essential tool to increase the efficiency of power amplifiers. Time and cost historically have forced vendors to perform load-pull during design, but now the speed, ...

In load pull calculations, power amplifiers are going to need harmonic load pull analysis and load pull contours with wideband electromagnetic tuners. Working with RFIC power amplifiers is difficult ...

Rohde & Schwarz is claiming to have invented a new test set-up for verifying power amplifier performance when connected to an antenna, which typically shows a dispersive impedance, by swapping the ...

In general terms, power amplifiers (PAs) used in communications systems must be large enough to amplify envelope peaks. This leads to amplifiers designed to offer the best efficiency at peak power ...
