TUMA10: True wideband load pull

Presentation Abstract
Load pull is a common technique to understand the behavior of RF frontends with varying conditions and matchings in the target application, optimize the DUT or create accurate models. RF front ends often drive signals into antennas which are nominal 50 Ohm, but in reality far off. As PA performance changes with different impedances, the only way to ensure proper performance is to test with the target signals and varying impedances, thus wideband loadpull. A fast and cost-efficient solution will be discussed in this session.
