ATA8352 UWB Device Overview

The ATA8352 device is a low-power ultra-wide-band (UWB) transceiver with an integrated security layer for secure distance bounding, localization and point-to-point data communication. The ATA8352 UWB device’s digital transmitting circuitry ensures maximum flexibility in the generation of UWB pulse signals.

The transmitter can perform the following functions:

• Generate a carrier frequency between 6.2 GHz and 8.3 GHz
• Ensure ETSI and FCC regulation compliance with programmable transmitted peak output power up to a typical value of 11 dBm

The ATA8352 UWB device front-end (FE) receiver provides an excellent sensitivity to guarantee a superior link budget for the RF communication. The digital base band signal processing unit ensures a highly stable sub nanosecond time-of-arrival (ToA) estimation. The ATA8352 UWB device includes a MAC layer for a secure distance-bounding measurement and data communication for proximity-based access control. The layer can be configured to ensure different degrees of security while providing a sufficient number of distance measurements to be run in one secure access control session.
