In this laboratory,we are now focusing our researches on the following areas: (1) High speed, high linearity and low noise system LSI components for wireless communications systems. (2) Wideband RF front-end components for ultra-wideband (UWB) applications. (3) Digital Radio or Digital RF Processor and its system components i.e. Digitally assisted RF/Analog circuits such as ADPLL (All-digital phase locked loop), DCO (digitally-controlled oscillators), sampling mixers, digital controlled PA, LNA etc. for Software defined radio or other reconfigurable applications. (4) Electrically small antennas for narrow band and UWB applications. (5) Interconnection and packaging technology of a chip to an antenna to reduce parasitic components.

Campus tour is offered annually to the high school students in Japan. Open campus give students the opportunity to meet academic staff, tour campus and learn more about major and programs offered by Kyushu University.
At the start of the tour, Prof. Dr. Kanaya gave students an idea about the scope of research in our laboratory and applications in wireless and cellular communications. In addition, the basic concept of building blocks in RF system and the circuit design of analog/RF ICs for wireless communication were introduced to the students. The tour concludes with the demonstration of the prototype co-developed by our laboratory and industry. Various methods of measurements were conducted to show the magnitude and phase from the output of the device as a function of frequency.
This tour offers a glimpse into the collaborative research efforts between academia and industry to overcome challenges in a rapidly changing world of wireless and mobile communications system.
