This paper shows activities of the ultra wideband (UWB) research and development consortium organized by the National Institute of Information and Communications Technology (NICT). Fully CMOS monolithic microwave integrate circuits (MMICs) are designed and fabricated both for the multiband OFDM and the impulse radio. UWB transceivers are constructed with the MMICs as their front-end devices and evaluated by some measurements such as time domain waveform, spectrum, error vector magnitude, and so on. To show the application capabilities of the UWB transceivers, two kinds of video transmission system are constructed and demonstrated.
