Outline of Final Research Achievements

As evident from the recent and rapid growth of 4G smart phones, I-phones, wireless LAN, RFID tags, ETC systems and so on, there are ever increasing demands of high performance, small size, and high speed microwave devices, circuits, components to realize more seamless Ubiquitous society. Software defined radio utilizing Cognitive radio technology is a means for realization. The whitespace frequency band available after the end of analog TV broadcasting technology has been the target of this research and a high efficiency tunable CMOS power amplifier was proposed in this research.
