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 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 ...
The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
