Abstract
The main objective of this paper is to present a calibrated mixed-signal characterization measurement system with an application case focusing a power amplifier (PA) digital pre-distortion (DPD scenario. This system allows to extract behavioral models radio-frequency (RF) mixed-signal components or devices, ranging from analog-to-digital converters (ADC), digital-to-analog converters (DACs) and integrated system-on-a-chip (SoC) integrated receiving and transmitting blocks, which are extracted in a scattering parameters notation and called D-parameters. It is developed on a modular PXI platform from National Instruments (NI) and will be employed in a illustrative power amplifier (PA) digital pre-distortion (DPD) feedback loop use case.
