RF amplifier efficiency

Webinar: RF amplifier efficiency

This webinar is intended for engineers and researchers who work on RF frontend designs and are facing energy efficiency challenges. While most of the parameters such as output power and frequency are standardized it is still possible to improve the energy efficiency by selecting optimal semiconductor technology, and by implementing efficiency enhancement schemes.

We discuss how fundamental techniques such as load modulation, supply modulation, and waveform engineering can be optimaly mixed to define the maximally efficient amplifier. Learn how you can get close to the theoretical efficiency limit while leveraging the techniques, with a suitable scheme.


Gareth joined Rohde & Schwarz in 2015, as a Senior Expert. His topics of interest include measurement-aided design methodologies for high efficacy RFFE (Radio Frequency Front Ends), supra-clock rate vector signal generation and analysis (e.g. higher bandwidth than clocking rates of ADC/DACs.), and vector signal calibration methods. Until joining R&S, he worked various engineering and management roles, in different industries, for major companies incl. Ericsson, Huawei, TriQuint (now Qorvo), Andrew Corporation (now Commscope) and ZTE. To date, he is the primary named on 7 granted patents. He graduated from the University of Leeds in 1994 with an Honours degree in Electronic & Electrical Engineering.
