ATA835x Ultra-Wide-Band (UWB) Transceivers

Microchip Technology ATA835x Ultra-Wide-Band (UWB) Transceivers feature an integrated security layer for secure distance bounding, localization, and point-to-point data communication. The ATA8350 device's digital transmitting circuitry ensures maximum flexibility in the generation of UWB pulse signals. The transmitter is able to generate accurate pulse durations ranging from less than 1ns to more than 10ns with a controlled envelope shape. The devices can also generate a carrier frequency between 6.2GHz and 7.8GHz and ensure ETSI and FCC regulation compliance with programmable transmitted peak output power up to a typical value of 9dBm. The ATA8350 Front-end (FE) receiver provides excellent sensitivity to guarantee a superior link budget for the RF communication. The digital baseband signal processing unit ensures a highly stable sub-nanosecond Time-of-Flight (ToF) measurement.  The ATA8350 includes a MAC layer for secure distance-bounding measurement and data communication for proximity-based access control. The layer can be configured to ensure different degrees of security.
