Abstract :
This paper presents the requirements on the preselect-filter for UWB applications for different Front-End linearities and interference scenarios. A procedure to calculate the minimum out of band attenuation was developed in order to achieve a high system performance in presence of interferer. A filter diagram is proposed for a robust UWB communication. Results show which UWB-bands are affected by narrow-band systems and how the receiver linearity can be traded off against preselect-filter requirements. The frequency band between 7.7 and 8.2 GHz could be identified as less influenced by intermodulation products. Therefore this band is highly recommended for communication of sensitive data.
