He held an NSERC Industrial Research Chair (IRC) for two terms (2001-2005) and (2006-2010) . Prior to joining the University of Waterloo in January 2000\, Dr. Mansou r was with COM DEV\, a global manufacturer of space hardware in Canada\, o ver the period 1986-1999\, where he held various technical and management positions in COM DEV’s Corporate R&D Department. Professor Mansour holds 42 US and Canadian patents and more than 400 refereed publications to his credit. He is a co-author of the highly successful Wiley book “Microwav e Filters for Communication Systems\, Fundamentals\, Design and Applicatio ns\,” an in-depth look at the state-of-the-art in microwave filter desig n\, implementation\, and optimization. He has also contributed 6 chapters to four other books. Professor Mansour founded the Centre for Integrated R F Engineering (CIRFE) at the University of Waterloo https://uwaterloo.ca/c entre-integrated-rf-engineering/. It houses a clean room and a highly adva nced RF test and characterization laboratory. He served as the Technical P rogram Committee (TPC) Chair of the 2012 IEEE International Microwave Symp osium (IMS). Professor Mansour is a Fellow of the IEEE\, a Fellow of the C anadian Academy of Engineering (CAE)\, a Fellow of the Engineering Institu te of Canada (EIC). He was the recipient of the 2014 Professional Engineer s Ontario (PEO) Engineering Medal for Research and Development and the 201 9 IEEE Canada A.G.L. McNaughton Gold Medal Award.\n\nPRESENTATION\n\nMULTI -FUNCTION MULTI-BAND RECONFIGURABLE HIGH-Q FILTERS\n\nReconfigurable filte rs are key components in the development of agile multi-standard receivers . The advent of innovative switched capacitor arrays and switch technologi es based on Silicon on Sapphire\, Micro-Electro-Mechanical Systems (MEMS) and Phase Change Material (PCM) technologies permits the development of a new generation of high linearity\, low loss\, and low power consumption tu nable components. In this new generation of reconfigurable microwave front -ends\, microwave reconfigurable filters are among the most critical and c hallenging components to perform adaptive frequency-band selection. This D ML talk starts by addressing the needs for using multi-band and tunable fi lters in wireless communication systems and in flexible satellite payloads . It then addresses existing tuning technologies\, providing a comparison between piezoelectric\, Semiconductor\, MEMS and PCM tuning elements in te rms of linearity\, insertion loss\, suitability for use at millimeter-wave frequencies and ease of integration with high-Q filters. It outlines majo r design considerations for tunable filters presenting techniques to reali ze tunable filters with an absolute constant absolute bandwidth and a cons tant frequency spacing between transmission zeros\, over a wide tuning ran ge. The talk also illustrates examples of tunable filters and diplexers tu ned only a by single tuning element\, while exhibiting a constant absolute bandwidth. It then addresses approaches for realizing multi-band filters including dual-band and triple-band filters. Finally\, it presents techniq ues for realizing multi-band filters where the various bands are tunable i n both center frequency and bandwidth.\n\n[]\n\nVirtual: https://events.vt ools.ieee.org/m/302995 LOCATION:Virtual: https://events.vtools.ieee.org/m/302995 ORGANIZER:jmmoskal@ieee.org SEQUENCE:6 SUMMARY:Multi-Function Multi-Band Reconfigurable High-Q Filters URL;VALUE=URI:https://events.vtools.ieee.org/m/302995 X-ALT-DESC:Description: <br /><div>\n<p class="yiv1897867422MsoNormal"><str ong>BIOGRAPHY</strong></p>\n</div>\n<p class="yiv1897867422MsoNormal">Raaf at Mansour is a Professor of Electrical and Computer Engineering at the Un iversity of Waterloo and holds Tier 1- Canada Research Chair (CRC) in Micr o-Nano Integrated RF Systems.
