MITSUBISHI ELECTRIC CORPORATION Mitsubishi Electric Corporation (TOKYO: 6503) and Tohoku University announced today their development of a 5GHz/60GHz dual-band receiver RF front-end Si-CMOS IC for a highly dependable and high-speed wireless communication system that Tohoku University has proposed as the “Dependable Air.” Technical details of new Si-CMOS IC will be announced during European Microwave Week 2014 from 5-10 October 2014.
Wireless communication is greatly dependent on high dependability and high speed. But since high-speed wireless communication normally uses millimeter-scale radio waves, communication can be established only in line of sight. In the 5GHz band used for wireless LANs, however, communication is possible over the horizon. Tohoku University is proposing its Dependable Air with wireless handsets that use multiple standards (heterogeneous) to conduct seamless handovers according on the environment.
Mitsubishi Electric’s new RF front-end IC is a miniaturized multiband model that uses the 5GHz and 60GHz bands. Size was reduced about 30% by sharing parts of the 5GHz and 60GHz RF front-ends.
Mitsubishi Electric also reduced the extent of trial IC manufacturing by introducing electro-magnetic simulation of performance effects in millimeter-wave bands for assembled ICs.
Going forward, Mitsubishi Electric plans to pursue standardization of this wireless communication, including IEEE802.11 and other standards, as well as develop RF-IC business for millimeter-wave communication devices.

The Dependable Air by Tohoku University is supported by the CREST funding program of the Japan Science and Technology Agency. Under the CREST project named “Fundamental Technologies for Dependable VLSI System” (research supervisor: Dr. Shojiro Asai), research into the “Development of Dependable Wireless Systems and Devices” (principal investigator: Prof. Kazuo Tsubouchi, Tohoku University) is being carried out.

About Tohoku University
Tohoku University, formerly known as the Tohoku Imperial University, was founded in 1907. From its start, it displayed to the world an unswerving commitment to an "Open Door" policy. Departing from the norms of other imperial universities, it accepted graduates from technical schools and higher normal schools, and despite opposition from the government at that time, became Japan's First University to admit female students in 1913.
Tohoku University has been committed to the "Research First" principle and "Open Door" policy since its foundation, and is internationally recognized for its outstanding standards in education and research. The university contributes to world peace and equity by devoting itself to research useful in solving societal problems, and educating human resources in leadership skills.
About Japan Science and Technology Agency
The Japan Science and Technology Agency (JST) is one of the core institutions responsible for the implementation of science and technology policy in Japan, including the government’s Science and Technology Basic Plan. From knowledge creation—the wellspring of innovation—to ensuring that the fruits of research are shared with society and Japan’s citizens, JST undertakes its mission in a comprehensive manner. JST also works to provide a sound infrastructure of science and technology information and raise awareness and understanding of science and technology-related issues in Japan.
