Pulsed UWB Transmitter for Military/Professional applications

Medium Bit rate Long Communication Links (>100m)

Ranging/Localization in indoor/urban environments

Through Wall Imaging capability to be considered

Robust against jamming/detection

Ultra Low power Pulsed UWB Transmitter for Intelligent Sensors applications

High Bit Rate short communication links (>1Mbit/sec, 2-3m)

Ultra Low power requirements

TDMA techniques to share the same physical channel avoiding collisions


UWB TX is the right solution

Ultra low power UWB TX developed in 3.1-5GHz band 1Mbit/sec short range link (2-3meters range) Power consumption scalable with Bit Rate exploiting duty cycle (TX

LOCALIZATION

Pulsed TH UWB

UWB TX developed in 3.1-5GHz band: large bandwidth provide good time resolution for localization

BPSK,ppm modulation as in IEEE 802.15.4a Power consumption of the transmitter is not a critical factor Emissions are critical due to probability of being detected
