Abstract
Each of the various methods for mixed-mode load-pull measurements, which can be found in literature, has its own advantages and disadvantages. In this publication, we analyze two of the most commonly used setups and a third setup of which we provided an initial treatment in a previous publication. We investigated the impact of 180° hybrids on the tuning capabilities of a mixed-mode load-pull system. Furthermore, we provide a rule-of-thumb to easily estimate this impact using only some specifications of hybrids. For all analyzed setups, we use measurement results to show that the tuning range of the newly proposed setup is superior compared to the other setups, though hardware effort and tuning complexity are greater.
