Ultra Wide Band (UWB) wireless systems based on impulse radio have the potential to provide very
high data rates over short distances. One of the solutions for the UWB communication systems is
the Multi Band On-Off Keying (MB-OOK) which consists in an OOK modulation generalized over
multiple frequency sub-bands and associated with a demodulation based on a non-trivial energy
threshold comparison. This article presents the analysis and simulations of an UWB MB-OOK
transceiver in the 6-8.5GHz band. This study is focused on the bandpass filter bank in the
transceiver’s architecture. The use of a Bulk Acoustic Wave (BAW) filter bank in the transceiver is
considered. Finally, system performance is estimated for the proposed architecture.
