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 ...

On visiting a high-performance GaAs fab, I was shown a problem with the measurement system. The on-wafer test system was calibrated using a power meter and on-wafer standards, using the built-in ...

Figure 1. Schematic of a Doherty PA Techniques such as Doherty amplifier structures extend high-efficiency device operation to lower power levels, allowing for significantly improved average PA ...

Standby power refers to the electric power consumed by electronic appliances while they are switched off or in a standby mode – but still connected and still drawing power. Fundamentally, standby ...
