James J. Komiak (M’89-SM’90-F’05) received a Ph.D. in Electrical Engineering from Cornell University in 1978. Dissertation research developed the “Real Frequency Technique” for broadband matching an arbitrary load to a resistive generator. He has 37 years of experience in system, module, and MMIC design for EW, communication, and radar applications. He has over 100 publications and 13 patents. He was elected to the grade of IEEE Fellow in 2005 for “Contributions to Monolithic Microwave Integrated Circuits, High Power Amplifiers, and Transmit/Receive Modules.” In addition, he was inducted into the Association of Old Crows Electronic Warfare Technology Hall of Fame in 2008. Dr. Komiak is an IEEE MTT-S Distinguished Microwave Lecturer (2014-2016).


Microwave and Millimeter Wave Power Amplifiers: Technology, Applications, Benchmarks, and Future Trends

Solid State Transistor Device Technology is ubiquitous in communications, radar, electronic warfare, and instrumentation applications. This presentation will cover Si BJT, Si LDMOS, MESFET, HBT, PHEMT, InP HEMT, MHEMT, and GaN HEMT. Content includes principles of operation, structures, characteristics, classes of operation, and device state of the art benchmarks. The art of power amplifier design is approached from a historical perspective. Power amplifiers utilizing these device technologies covering UHF through sub-millimeter wave are described including amplifier state of the art benchmarks. Future trends are highlighted and summarized.
