Overview:
OSU Wireless Design Projects
EE682R is design course where senior undergraduate students
work in teams to
design RF/microwave circuits to built a wireless
communication system.

OSU Wireless Design Projects in 95, 96, 97, 98 and 99
The 95-99 projects involved the students in the design
of the RF front end of a 2.4-2.485 GHz 1 mW wireless VCR-TV link.
the transmitter and receiver integrated various components such as,
patch antennas, low noise amplifiers, voltage control
oscillators, attenuators, mixers, transmission filters,
and in 98 and 99 a PLL and a microprocessor to control it.
A Doppler radar was also completed in the 99 offering
of the wireless design course.
The 1999 Wireless Design Class
Highlights of the 99 wireless 582/682R included a transmitter with
an LO rejection mixer to reduce the LO leakage radiated.
Both receiver and transmitter up- and down converted two
different channels (VCR source and frequency hopping control channels).
The VCR signal were preamplified before up-conversion.
The frequency hopping of the receiver and transmitter VCO-PLL was
controlled by a microprocessor. A second project featured
a Doppler radar with a patch array antenna and a detection circuit.

Wireless design course:
DANIEL ADAMS, AZAH AHMAD, JOSHUA BAILEY, JULIE BEDNARCZYK, MICHAEL BILLY, STEVEN BHASIN SUMMIT, BLACKSTONE, KRISTOFFER BRUVOLD, ROBERT CAMERON, DENISE CECULSKI, KEA CHIN, CHRISTIAN DIVIS, EUSEBIO ARIEL, MICHAEL HRIPKO, JOONG-HO KIM, CHARLES KIRKENDALL, MARK KUCALABA, JOHN LUKEZ, TRAVIS MONKE, ERIK OLSEN, CHRISTOPHER PAWLAK, KEVIN SAHL, BRIAN SMITH, SCOTT SOOTS, WEI-LOONG YEOH, SEOUNG-JAE YOO, MARK ZAIM, FABIAN GRIFFITH, KOUNT ARIEL, and VU LE,
with several Professors who kindly served as reviewers of their design projects.

Both technical breadth and leadership ability is required of our students
to organize themselves and complete
in a strict 10 week time frame,
the design, fabrication testing and demo
a wireless system from the antenna to the microprocessor control.
The 1997 Wireless Design Class
The 97 design course included
BENTLEY DONALD, CAVENER BRYAN, COLLA KRISTEN, DEJESUS RAYMOND, GOH SING, HARNIST KEVIN, HASAN ZULKIFLY, JARUPAN BOANGOAT, NORMAN JASON, ROBINSON PAUL, ROWLAND D, SCHERER THOMAS, TAN SIAO, TROUT KEVIN, TROYER JERALD, and PROCHASKA STEVEN,
who were divided in three teams.
Some of the inovation pursued by the 97 design
included an attenuator to stabilize the
VCO followed by an amplifier to properly drive the mixer.
The 1996 Wireless Design Class
The 96 design courses included:
NICLEY KERI, BUXTON MARK, RUSSELL AARON, COUCH DAVID, GROMLEY NEIL, SYED AHSAN,
WHITEHEAD WAYNE, SIMON KIT, TJANGNAKA WILBERT, SANTOSO DANY, BALAJI RAGHAVARCHARI, REEHAL GIURSHARAN.
This original design worked but the VCO unstability made tuning
difficult.
