A Novel Active Differential/Common-Mode Load for True Mixed-Mode Load-Pull Systems

A novel active load-pull system with differential and common-mode load tuning capability is presented in this paper. The system is able to measure and tune, without the limitations of passive systems, both differential and common-mode loads independently, and to monitor most of the interest performa...

Description
Summary:A novel active load-pull system with differential and common-mode load tuning capability is presented in this paper. The system is able to measure and tune, without the limitations of passive systems, both differential and common-mode loads independently, and to monitor most of the interest performances, as differential and common-mode output power, in real-time. The novel system has proven to be a crucial tool for the characterization of active differential devices
