Digital Radio transmission for applications such as short distance radio links, like UWB (Pulsed or MBO, low and high data rate), Bluetooth, Zigbee and the like, is coming closer to become reality. The main challenge to overcome is to port Digital Radio to Cellular (DCS, W-CDMA), which can be achieved by the ¿software radio¿ approach. Using generic hardware and software provides easier configurability and hardware re-use with different standards. The major bottleneck towards the ¿software radio¿ is the highfrequency part of the radio transceiver. Signal conversion from analog-to-digital or from digital-to-analog right at the antenna with Nyquist rate converters is far beyond what state of the art technology is able to deliver. An alternative solution to bring the digital-to-analog interface closer to the antenna in the transmitter is using a bandpass delta-sigma modulator. It allows generating a radio-signal with a high signal-to-noise ratio in a narrow band around the carrier. The drawback of that approach is the amount of filtering required at the transceiver output to remove quantization noise appearing outside of the useful signal band. The reconfigurability of such a transmitter for multi-mode communication systems relies on the appropriate filters for the different frequency bands and on the possibility to reconfigure the power amplifier to address different bandwidth and power requirements. A high-performance and low-cost power-filtering technology is therefore a key-factor in the development and future adoption by the industry of that technology. New technologies like nanometric MOS transistors (65 nm CMOS and in the longer term 45nm CMOS), and MEMS technologies such as Bulk Acoustic Wave (BAW) resonators, are the building blocks that will be used to achieve this objective. The scientific and technological objectives of MOBILIS are thus to demonstrate the feasibility of a mixed SoC (nanometric CMOS/system integration) and SiP (BiCMOS/power-BAW) RF power transmitter, based on a Digital Radio transmitter architecture, addressing both the WCDMA and DCS standards. Manufacturability of the system is addressed as well, through the development of an integrated test bench for the BAW devices, making it possible to validate the components and monitor their evolution with a built-in-self-test (BIST) approach. The MOBILIS project addresses one strong element of the IST call which is Nanoelectronics.
