Vacuum Electronics Applications in mmWave SatCom Systems
Dr. Alan Palevsky
Senior Engineering Fellow
System Development Center for Space and Airborne Systems (SAS)
Dr. Palevsky will discuss his views, from the perspective of a large system house, on the current state of RF systems and applications. This includes current state‐of‐the‐art, present‐day and future directions, in particular mm‐wave systems, and the technological landscape vis‐à‐vis both solid state and vacuum RF technologies.
Dr. Alan Palevsky has been at Raytheon 34 years. His work has spanned four different product areas. He started at Microwave and Power Tube Division (MPTD) building high power microwave tubes. Next he worked at Raytheon Research Division (RD) developing GaAs microwave MMICs. Third, he was the technical lead at Quincy developing High Brightness Flat Panel Displays. Since 1998 he has been at Raytheon Marlborough working as a System Engineer on multiple programs and as a Microwave Engineer on the SatCom product line. He has also been a technical leader in the development and utilization of simulation based design tools and techniques. He has four patents.
Dr. Palevsky has degrees of BA in Mathematics and Physics from Williams College, Magna Cum Laude, Sigma Xi (1973) and a PhD. in Physics from MIT (1981). The subject of his thesis was the Relativistic Magnetron. Part of that work included the development of a 2½ D fully relativistic electromagnetic particle-in-cell code.
Pluto Revealed: First Results From The Historic 1st Fly-By Space Mission – Innovations In Communicating With A Deep Space Probe
Dr. Kimberly Ennico
Deputy Project Scientist on the New Horizons Pluto Fly-By Mission
NASA Ames Research Center
Dr. Ennico will describe the New Horizons mission and its historic flyby of the dwarf planet Pluto in July 2015. Particular emphasis will be placed on the redundant Traveling Wave Tube Amplifier communications system and the novel methods used to maximize data transfer back to Earth. Spectacular visuals will undoubtedly be a part of the presentation as well.
Dr. Kimberly Ennico is a research astrophysicist at NASA’s Ames Research Center. She is a Co-Investigator and Deputy Project Scientist on NASA’s New Horizons Pluto Fly-by Mission, leading the calibration activities and doing compositional mapping of Pluto and Charon with color imagery and spectroscopy. Dr. Ennico is also an Instrument Scientist for the Near-Infrared Volatile Spectrometer System instrument in the Regolith & Environment Science and Oxygen & Lunar Volatile Extraction lunar payload suite and an Instrument Scientist for the Mid-Infrared Spectroscopy Mode for the Stratospheric Observatory for Infrared Astronomy FORCAST Instrument. She is also a Principal Investigator developing innovative telescope designs using small satellites and is actively working to mature low-cost, quick turn-around suborbital and balloon payloads that deliver focused science measurements and promote broader hands-on experience. Her prior space mission experience includes being Instrument Scientist on the Spitzer Space Telescope Far-Infrared camera MIPS, specialist in detector radiation testing for the James Webb Space Telescope, and Payload Scientist and Integration & Test Lead for the Lunar Crater Observation and Sensing Satellite, where she successfully demonstrated a cost-effective Class D test program of modified COTS hardware.
The Edge: Linearization
Dr. Allen Katz
Linearizer Technology, Inc.
Dr. Katz will discuss the decision to use linearization with microwave and millimeter-wave high power amplifiers. Emphasis will be placed on amplifiers employing traveling wave tubes (TWTs) and their comparison to recently available GaN FET power devices. The tradeoffs between digital and analog linearization will be considered, along with the challenges of broadband multi-GHz and multi-octave linearizer design.
Dr. Allen Katz is a professor of Electrical/Computer Engineering at The College of New Jersey. He is founder and President of Linearizer Technology, Inc, which now includes Linear Photonics, LLC and Linear Space Technology, LLC. He received his doctorate and baccalaureate degrees in electrical engineering from New Jersey Institute of Technology and a master’s degree in electrical engineering from Rutgers University. Prof. Katz holds 17 patents and has written over 100 technical publications. He received the IEEE’s Microwave Society’s (MTT-S) Application Award in 2015 for his work in linearization, the IEEE Microwave Magazine Best Paper Award in 2010 and the William Randolph Lovelace II Award for outstanding contributions to space science and technology from the American Astronautical Society in 2002. He is also recipient of the IEEE Region 1 Technology Innovation Award in 2007. He was an MTT-S Distinguished Microwave Lecturer and is a Fellow of the IEEE. He is chair of the AP/ED/MTT chapter in the IEEE Princeton/Central Jersey Section and has served the IEEE in many capacities.
Audio Vacuum Tube Amplifiers, Still Dominant After All These Years
Dr. Anthony Triolo
Scientific Research Manager
Dr. Triolo will discuss the topic of audio tube amplifiers, and the passionate following that these devices have among true audiophiles. Dr. Triolo’s personal experience as a signal processing expert and a musician will help explain why “warm tube sound” is often preferred over high fidelity solid state audio amplifiers.
Dr. Triolo has been with Vencore Labs since 2001 (originally Telcordia Applied Research) and currently serves as a Scientific Research Manager in the Wireless Systems and Networks Research department. He holds a Ph.D. in Electrical Engineering specializing in Electromagnetic theory. He was previously a Member of Technical Staff at Lucent Technologies Bell Laboratories in the Wireless Forward Looking Research lab. Dr. Triolo has led efforts in areas related to propagation measurement and modeling, antenna and power amplifier design, spectrum management, and cognitive radio architecture and operation. He holds several patents and has published many journal articles in areas related to signal processing techniques, cellular system analysis, planning, and simulation, software architecture and design, and radio system analysis and design. While at Bell Labs, Dr. Triolo led an effort to improve the efficiency of multi-carrier cellular base station amplifiers through use of a combination bias-modulation and digital predistortion techniques.
Dr. Triolo has led many projects while at Vencore Labs, including efforts to measure and characterize RF propagation leading to generation of empirical channel models for inclusion in the Vencore Labs in-house propagation modeling tool. Dr. Triolo is currently leading an effort to develop a distributed detection and classification system using low-cost Software Defined Radio platforms.
