The paper provides an overview of the current and emerging
filter technologies for wireless system applications.
Detailed comparisons are given for the various filter
technologies used in both base-station and mobile handsets
applications. Coaxial, dielectric resonator (DR) and
high temperature superconductor (HTS) technologies are
addressed for base-station applications while ceramic,
multilayer dielectric, surface acoustic wave (SAW) and
film bulk acoustic resonator (FBAR) filters are considered
for mobile handsets applications. The current development
efforts in each filter technology area are also highlighted.
Biography
Dr. Mansour received the Ph.D degree in Electrical
Engineering from the University of Waterloo, Ontario,
Canada in 1986. From 1986-1999, he held several key
positions at COM DEV’s Corporate R&D Department,
Cambridge, Ontario, where he was involved in the development
of novel miniature filters and multiplexers for space
and wireless applications. In January 2000, he joined
the University of Waterloo as a full Professor in Electrical
and Computer Engineering Department. He has over 80
journal and conference publications and 21 US and Canadian
Patents to his credit. He has contributed to many technological
advancements in the field of RF Engineering. Among his
achievements is the development of the world’s
first engineering models for HTS input and output multiplexers.
Prof. Mansour is a Fellow of the IEEE. He holds an
Industrial Research Chair on RF Engineering at the University
of Waterloo.
