A Baseband Time Domain Measurement System for Dynamic Characterisation of Power Amplifiers with High Dynamic Range over Large Bandwidths
2003 (English)In: Conference Record - IEEE Instrumentation and Measurement Technology Conference, 2003, 1177-1180 p.Conference paper (Refereed)
This paper describes, and discusses in some detail, a measurement system for dynamic characterisation of power amplifiers. The system uses data that are generated and collected at baseband to accurately calculate AM/AM and AM/PM distortion as well as memory effects in the amplifiers. The limitations of the system in terms of dynamic range and bandwidth are discussed as well as techniques to overcome them.
