  1. Agile Radio 1.05.25-5.85 GHz RF Module Design Goals 5 GHz Module Status • Develop modular Baseband to RF transceiver sections with extremely flexible frequency band and channel bandwidth capabilities. • Initial design will be used for experiments in the U.S. and European 5.25-5.35 GHz and 5.475-5.825 GHz UNII bands, with modules designed for other frequency bands to follow. • Support the Hyper-OFDM modulation concept, as well as other modulation formats of interest. • Incorporate hardware features useful to the research and academic communities, such as digital gain controls for RF channel sounding and characterization experiments. • Proof of concept 1.0 prototype assembled. • RF and Control circuitry tested and characterized. • Prototype has met performance expectations. • Integration with 1.0 Agile Radio Digital Module for further testing and circuit optimization is in process. • 2.0 Agile Radio 5 GHz RF Module design is in process; redesign will incorporate minor tuning changes and layout reorientation to match the version 2.0 Digital Module. • Field tests planned for Summer 2005.
