Large Signal Analysis and Waveform Engineering
AMCAD HPR727A wideband comb generator has been developed for the characterization of nonlinear RF devices (transistors, amplifiers), enabling the measurements of absolute phase of the harmonic content of a signal and allowing Waveform engineering capabilities in time-domain Load-Pull.
Waveform engineering can be used to minimize the power consumption and to optimize the power added efficiency of amplifiers, operating in a switch-mode class of operation like Class F or inverse Class F. See IVCAD MT930GA Large Signal Analyzer operating manual
Used in combination with IVCAD Software, this Comb Generator enables accurate phase-calibrated measurement of harmonic signals when measured with a Vector Network Analyzer, in order to provide true RF waveform measurements at the DUT reference plane.
This phase calibration standard allows optimizing the operating class of RF transistors using harmonic load tuning with IVCAD MT930C VNA based load-pull measurement bench control and IVCAD MT930GA Time-Domain LSA software module.
