Title: Technical Considerations for Testing 5G Base Station Finals for Digital Pre-distortion (DPD) Characterization
Date: August 4, 2021
Time: 8:00am PT / 11:00am ET
Sponsored by: AR RF/Microwave Instrumentation
Presented by: Dale Hauck, Applications Engineer
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 provide a near distortion-free 3GPP test model. Peak to average ratio of these test models may exceed 14 dB. Class A amplifiers are the expected solution. This presentation will discuss applicable amplifier specifications such as P1dB in addition to parameters of the entire RF chain.
