Load pull characterization is an essential tool to increase the efficiency of power amplifiers. Due to time and cost, vendors have historically performed load pull during design. Today, however, the ...

Mesuro announced the introduction of its MB Series active load-pull systems at IMS 2009. The MB Series enables device and power-amplifier manufacturers to characterize their devices within an ...

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 ...

One way to synthesize it is with an active load-pull measurement system, both in terms of impedance caused by device interaction and the natural impedance caused by the passive structure. The waveform ...
