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 ...
