Abstract
The capabilities of active load-pull are extended to be compatible with the characterization requirements of high-power base-station applications. The proposed measurement setup provides ultra-fast high-power device characterization for both CW, as well as, pulsed, duty-cycle controlled, operation. The realized system has the unique feature that it can handle realistic complex modulated signals like W-CDMA with absolute control of their reflection coefficients vs. frequency.
