• Supports 4 RF bands from 3.5 GHz to 6.5 GHz

• Programmable transmitter output power

• Fully coherent receiver for maximum range and accuracy

• Designed to comply with FCC & ETSI UWB spectral masks

• Supply voltage 2.8 V to 3.6 V

• Low power consumption

• Data rates of 110 kbps, 850 kbps, 6.8 Mbps

• Maximum packet length of 1023 bytes for high data throughput applications

• Integrated MAC support

• Supports 2-way ranging and TDOA

• SPI interface to host processor

• 23 mm x 13 mm x 2.9 mm 24-pin side castellation package

Key Benefits

• Simplifies integration, no RF design required
