If we could choose three things to illustrate the key concepts behind “load optimization,” the most apt would be a pair of scissors, a stopwatch and a dollar sign. First, the scissors. Cost cutting is ...

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 ...

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 ...

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 ...
