Semiconductor Electronics for High Power/High Speed Reconfigurable RF and Microwave Electronics

Dr. Robert H. Caverly
Professor of Electrical and Computer Engineering at Villanova University

Abstract: The microwave and RF design engineer always seeks to develop a design that will meet specifications the first time that the circuit is fabricated. To do so requires that as many elements and phenomenon as possible associated with the control devices and circuit be accurately modeled. In the case of the microwave and RF semiconductor control circuits, accurate modeling of the solid-state control components over frequency, voltage, current and power is key to successful control system design. This talk will cover material that will provide the RF and microwave design engineer insight into the physical operation and modeling of PIN diodes and field-effect transistors (FETs) as control components and their use in microwave and RF control circuits. The talk will cover basic RF and microwave control circuits for reconfigurable electronics, and then focus on linear and nonlinear behavior and models for PIN diode, MESFET and MOSFET control elements to implement these circuits. The talk will conclude with control circuit examples using these models for use in reconfigurable RF and microwave electronics.

Speaker’s Bio: Dr. Robert H. Caverly received his Ph.D. degree in electrical engineering from The Johns Hopkins University, Baltimore, MD, in 1983. He has been a faculty member at Villanova University in the Department of Electrical and Computer Engineering since 1997 and is a Full Professor. Previously, he was a Professor for more than 14 years at the University of Massachusetts Dartmouth. Dr. Caverly’s research interests are focused on the characterization of semiconductor devices such as PIN diodes and FETs in the microwave and RF control environment. He has published more than 100 journal and conference papers and is the author of the books Microwave and RF Semiconductor Control Device Modeling and CMOS RFIC Design Principles, both from Artech House. An IEEE Life Fellow, Dr. Caverly is currently the Editor in Chief of the IEEE Microwave Magazine and a Track Editor for the IEEE Journal of Microwaves. He is also an elected member of the MTT-S Administrative Committee as well as a member of the HF-VHF-UHF Technology and Biomedical Applications Technical Committees of the MTT Society.
