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 ...

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 ...

How accuracy is defined in DC programmable power supplies How and why the power supply experiences voltage output errors How to wire test leads and sense leads for accurate measurements When testing ...

The PPH25X PDK (process design kit) is specifically developed for high-frequency and high-power designs and is fully qualified by UMS. The process features very high breakdown voltage that achieves ...
