IWTh1: Wideband RF PA Characterization: VNA vs VSA/VSG Under Memory Effect Conditions

Presentation Abstract
Modern technology is driving higher data rates and wider bandwidths. Communication standards such as 5G, 802.11, and satellites are driving power amplifier (PA) designers to develop amplifiers with ever-wider bandwidths. As bandwidth increases PAs memory effects become more pronounced, making accurate memory effect characterization more critical than ever. Additionally, efficiency requirements push the PAs further into non-linearity. Both topics are critical for digital predistortion (DPD) techniques. Different instrument classes are available for measuring wideband PAs. This workshop will compare data obtained from vector network analyzers (VNAs) and from vector signal generator/spectrum analyzer setups.
