Comparison of Active and Passive Load-Pull Test Benches

Some load-pull test benches are developed at present time in different university laboratories. These characterization benches offer high capabilities and are well suited for the research activities. This paper presents the evolutions to apply the load-pull characterization technique issued from the research to the industrial world. This application involves choices to make. These ones are justified and detailed after descriptions of a research and an industrial load-pull characterization bench.
