The R&S® SMW-K546 software option aids the optimum design of multiple path amplifiers, including Doherty Amplifiers. This application note provides guidance on the use of the software option, both for direct control and programming via the touchscreen, and for remote control using SCPI. The software and associated techniques may similarly be used to develop other quasi-linear, multi-path amplifiers; including Balanced, Anti-Phase (so-called Push-Pull), Distributed, Spatially Combined, Load Modulated Balanced and many more.
