Unlike passive systems, active load-pull systems make it possible to overcome loss and reach all parts of the Smith chart. The classical Doherty architecture illustrated in Figure 1 consists of Main ...
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 ...
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 ...
R&S offers a load pull test setup with wideband modulated signals using the RTP oscilloscope for non-linear device characterization. Compared to conventional vector network analyzers, this setup ...
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 ...
