This webinar  highlights the surprising yet counter-intuitive property in quadrature-balanced amplifiers that allows active load modulation of the output match presented to the balanced transistors, which has opened new avenues in high-efficiency RF power amplifier design for both commercial and aerospace/defense communications applications.

Presenter Bio:
Dr. Steve C. Cripps obtained his master’s and Ph.D. degrees from Cambridge University in the 1970s. After working for several years with the pioneering gallium arsenide (GaAs) group at Plessey Research, he emigrated to the U.S., where he worked for 15 years in various engineering and management positions at Watkins Johnson, Loral, and Celeritek. In 1996 Dr. Cripps returned to the UK, working as an independent consultant before taking on an academic post at Cardiff University, where he is currently a distinguished research professor. Dr. Cripps 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. Dr. Cripps is an IEEE Fellow was the 2008 recipient of the IEEE Microwave Application Award.
