Dr. Jeff Powell

Professor Steve C. Cripps obtained his Ph.D. degree from Cambridge University, England. He worked for Plessey Research (now GECMM) on GaAsFET hybrid circuit development. Later he joined Watkins-Johnson's solid state division , Palo Alto, CA, and has held Engineering and Management positions at WJ, Loral, and Celeritek. During this period, he designed the industry's first 2-8 Ghz and 6-18 Ghz 1 watt solid state amplifiers, and in 1983 published a technique for microwave power amplifier design, which has become widely adopted in the industry.

In 1990 Professor Cripps became an independent consultant and was active in a variety of commercial RF product developments, including the design of several cellular telephone power amplifier MMIC products. In 1996 he returned to England, where his consulting activities continue to be focused in the RF power amplifier area.

In 2006 Professor Cripps published a second edition of his best-selling book, "RF Power Amplifier Design for Wireless Communications" (Artech House). He is currently vice-chair of the High Power Amplifier subcommittee of the Technical Co-ordination and Technical Program Committees of the IEEE Microwave Theory and Techniques Society, and writes the regular "Microwave Bytes" column in the IEEE Microwave Magazine. He recieved the 2008 IEEE Microwave Applications Award.

Dr Cripps has been a member of the Continuing Education Institute-Europe Faculty since 1995, and is a Professorial research fellow at Cardiff University, UK.


Dr. Powell received his Ph.D. in 1996 from the University of Birmingham, UK.

Since then he has worked in the field of microwave component design and packaging, using MMIC and hybrid circuit techniques in multiple technologies and for various applications. Dr. Powell was a Principal Microwave Engineer at QinetiQ, UK, between 2001 to 2011 where he designed a wide variety of circuit functions using GaAs, InP and GaN technologies in the frequency range 1 GHz to 110 GHz. He also contributed to the development of a GaN MMIC process at QinetiQ, demonstrating GaN MMIC components. He currently works as a freelance design engineer working for a variety of industrial and university clients.

Dr Powell has published more than 40 papers and 2 issued or pending patents and has made many technical presentations at international conferences and seminars.

Dr Powell has been a member of the Continuing Education Institute-Europe faculty since 2013.
