Fundamentals of RF and Wireless Performance Testing

Fundamentals of RF and Wireless Performance Testing

Personal communications have become ubiquitous in today’s society. Consider for a moment that modern smart phones may contain, in addition to a quad-band cellular transceiver, WLAN, GPS, and Bluetooth radios. As our need for wireless communications of all types continues to increase, engineers need a solid foundation on radio frequency and wireless principles. This course provides a system level overview of the building blocks of a modern digital radio. Participants will gain an understanding of the functions and performance parameters for each block. The course will then address the RF performance testing of the system and each component block, both for characterization with benchtop instrumentation and for production using high-speed, high-volume automated test equipment (ATE). Advanced topics addressing audience specific needs will also be discussed.

Currently Scheduled Course Dates

Instructor's Profile:Dr. Claudio Montiel

Claudio Montiel received his bachelor’s degree in electrical engineering in 1988 from the University of Hawaii at Manoa and joined Western Geophysical Company (Houston, Texas) where he served in seismic data acquisition crews in Africa and Latin America for three years. He received his Master’s degree in Electrical Engineering from Texas A&I University (Kingsville) in 1993 and his Ph. D. in Electrical Engineering in 1997 from Texas A&M University (College Station). He has over 12 years of experience in the area of RF/Wireless production testing of RFICs for both mobile and infrastructure applications. At IBM, he developed RFIC test solutions for Roos and Teradyne ATEs. At Texas Instruments, he worked on tester platforms from TI, Teradyne, and Verigy. He is currently an Assistant Professor of Electrical Engineering at Texas A&M University – Kingsville, where he teaches courses in electronics and RF/Microwave systems.
