Wireless Applications Engineer Teradyne, Inc., Wireless Business Unit Sept. 2000-
Provided technical support for test engineers using Teradyne FLEX, Catalyst, and A5xx automatic test equipment (ATE) to test wireless RF and microwave integrated circuits. Demonstrated cell-phone power amplifier test capability of FLEX platform. Developed first wireless FLEX application (for ISM-band FSK transmitter) and first quad-site, high-volume FLEX program for WLAN 802.11b/g transceiver.
Demonstrated product features to potential customers, playing a key role in multiple customer wins. Developed code to implement 802.11a OFDM WLAN modulation standard. Provided on-site training to customer engineers, and technical support to sales and marketing teams.
Led technical team to diagnose and resolve noise figure testing problems for demanding customer. Developed noise figure calibration procedure for FLEX tester. Developed novel algorithm for reducing effects of interference in noise measurements. Implemented and modeled low-phase noise RF frequency reference. Developed code library to support external GPIB synthesizer in customer application programs. Codified customer requirements for software and hardware engineers. Diagnosed problems reported by customer and field engineers.
Low Temperature Electronics
Researched electronic relaxation in normal metals using superconductor tunnel junctions. Constructed self-contained 300 mK He-3 fridge with fiber-optic feedthrough. Experience in photolithography, clean-room microfabrication, vacuum systems, cryogenic design, low-level signal measurement, and data collection and analysis using LabView and Igor Pro. Experience with Ti:sapphire mode-locked laser, producing femtosecond pulses for use in non-linear pump-probe measurements. Wrote Macintosh Common Lisp code to convert data formats, control GPIB devices, and control Igor Pro through low-level process-to-process communication. Wrote Perl scripts to parse web server logs. Used Fortran libraries to simulate thermal conduction in samples.
Programming work on a system that allows oncologists to plan and simulate treatment of patients with 3D graphics based on CT scans. Programmed in C (UNIX) on Stardent Titan vector mini-supercomputers. X Window experience. Implemented interface to AVS visualization software.
C/C++, Common Lisp, Fortran, Matlab, Tcl/Tk, Perl, UNIX, TeX/LaTeX, Visual Basic.
