Okinawa National College of Technology Uses AWR for Climatology Communication System
Okinawa National College of Technology, located in Henoko, Nago-city, Okinawa prefecture, has four colleges of technology, including the 850-student Department of Information and Communications Systems Engineering. The department trains students to become engineers with creative and practical skills useful in the information and communication field. Study areas include the fundamentals of computers, networks, optical and wireless communications, ICs, software, and signal processing. The college adopted Microwave Office® and Visual System Simulator™ (VSS) software as the tools of choice in 2006, and more than 40 undergraduate and graduate students currently use AWR software in their courses.
Professor Koyu Chinen specializes in optical, wireless communication, compound semiconductor, and high-frequency circuit technologies. He has many years of experience in the design of transmitter/receiver modules for optical communications systems (including 25 years at Toshiba) as well as compound semiconductor and optical/high-frequency device development.
Upon joining Okinawa National College of Technology, Dr. Chinen chose AWR design tools for his courses. “I began using AWR software in teaching not just because it was easy to learn but because it combines component-level circuit design with system-level and EM tools in a single environment. This is a great advantage to students learning microwave and RF concepts.”
The Designer Challenge
One of Dr. Chinen’s research projects focused on a large, complex system using WiMAX, optical communications, and a climate satellite from the U.S. National Oceanographic and Atmospheric Administration (NOAA).
Microwave Office software was used for circuit design, prototyping, and measurement, and VSS for system-level performance verification. The combination of AWR’s integrated circuit- and system-level design tools proved to be highly effective in the project’s networked concurrent design environment that included analog, digital, microwave, and optical technologies.
