Technical Considerations for Testing 5G Base Station Finals for Digital Pre-distortion (DPD) Characterization

The increased bandwidth and peak to average ratios of the 5G physical layer has amplified the need for accurate DPD characterization. Wide band DPD systems are in extensive development. Final amplifier stage gain can be as low as 10 dB. To accurately characterize its distortion, high power linear RF drive is required. This signal should […]
