Abstract

Load pull with active tuning has been reported for many years, but not widely implemented, even though it does offer some advantages. Load pull with passive tuning, however, is widely used. Combining active tuning with passive tuning creates a hybrid tuning system that offers some of the advantages of both approaches. This paper discusses a hybrid tuning system created by adding active tuning to an existing passive load pull system. Practical issues, including calibration, high power measurements and connection options, are also discussed.
