Fast Multiharmonic Active Load–Pull System With Waveform Measurement Capabilities
Artikel i vetenskaplig tidskrift, 2012
A novel fast multiharmonic active load–pull system is presented, which allows for the acquisition of the complete voltage and current waveforms. The system is capable of measuring multiple different load impedance or input power states within a short time instance (typically 180 states within 20 ms). It also facilitates high-power capability (up to 100 W) and high-frequency operation (up to 50 GHz). Furthermore, the dynamic range at the higher order harmonics is significantly improved by introducing an equalizer in cascade with the wideband harmonic samplers.
