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 ...

The MB series is the first commercially available active load-pull solution, according to its manufacturer. The system uses a new measurement architecture to evaluate rf waveforms, power spectrum, ...

RF and microwave devices need to operate as part of a system. Because they are typically not 50-Ω devices, they need to be matched to the rest of the system. That requires characterization of ...

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 ...
