Continuous modes have been widely recognized as the most significant new development in RF Power Amplifier (RFPA) design for 30 years. A simple piece of mathematical waveform synthesis reveals that full Class B efficiency can be obtained with a much wider range of harmonic terminations than classical theory has always stipulated. This enables RFPAs to be designed with greater bandwidth, and good linearity, at a constant high efficiency level. This introductory webinar covers the basic theory and a simple design example.
Prof. Steve C. Cripps, Distinguished Research Professor, Cardiff University, and Malcolm Edwards, European Technical Manager, AWR
Dr. Cripps obtained his Masters and Ph.D. degrees from Cambridge University in the 1970’s. After working for a few years with the peioneering Gallium Arsenide group at Plessey Research, he emigrated to the US where he spent 15 years holding various engineering and management positions at Watkins Johnson, Loral, and Celeritek. In 1996 he returned to the UK, and was an independent consultant, before moving to an academic post at Cardiff University, where he is currently a Distinguished Research Professor. He has authored several best-selling books on RFPA design, and is a regular contributor to the IEEE Microwave Magazine with his popular “Microwave Bytes” column. Prof. Cripps is a Fellow of the IEEE and was the 2008 recipient of the IEEE Microwave Application Award.
Malcolm Edwards was born in London, England, in 1950. He received a BSc. degree in electronics from the University of Wales Institute of Science and Technology. Since September 2000 he has been Technical Manager for AWR based in the UK engaged in technical support, product development and training. Before joining AWR, Malcolm worked as a principal engineer at IFR Ltd, Stevenage, England. During this period Malcolm developed ultra wide band harmonic mixers, low distortion reflection mixers and sampling gates for spectrum analyser applications. Previous work experience has ranged across a number of technologies including medium power Gunn oscillators for portable radar applications, satellite SSPA development for Inmarsat III, GaAs MMIC Gilbert Cell mixers, planar filters, medium power hybrid amplifiers and hybrid mixers.
