DW3120TR13

RF Transceiver ICS Overview

The Qorvo DW3120TR13 is a second-generation fully integrated pulse radio ultra-wideband (UWB) transceiver IC based on the IEEE 802.15.4z standard. It supports data rates of 850 kbps and 6.8 Mbps with a maximum frequency range of 6.4896 GHz to 7.9872 GHz. The device operates on a supply voltage of 1.5 V to 3.6 V, featuring receive current of 19 mA and transmit current of 17 mA. It offers ranging accuracy under 10 cm and angle measurement within 5 degrees. Packaged in a WLCSP-52, it supports SPI interface and operates between -40°C and +85°C.

RF Transceiver ICS Feature Summary

• Supports IEEE 802.15.4z BPRF mode for enhanced security features including AES encryption and secure flight time measurements.
• Enables precise location tracking with sub-10 cm ranging accuracy and less than 5-degree angle of arrival measurement.
• Facilitates interoperability with Apple U1 chips and complies with FiRa™ standards for certified development.
• Provides two antenna ports to support Phase Difference of Arrival (PDoA) implementations using a single chip.

RF Transceiver ICS Applications

• Mobile and consumer applications requiring low-power battery operation
• Industrial applications needing robust wireless communication
• Secure asset tracking and access control systems

RF Transceiver ICS Procurement Notes

Verify that the specific suffix TR13 corresponds to the reel packaging configuration as indicated by distributor listings. Confirm compatibility with existing system designs regarding the WLCSP-52 package dimensions and thermal requirements. Ensure the design supports the required SPI interface and voltage levels between 1.5 V and 3.6 V. Cross-reference the part number with official Qorvo documentation to confirm current production status and availability constraints.

RF Transceiver ICS Selection Notes

Select this component when high-precision indoor positioning and secure short-range communication are required. It is suitable for designs needing compatibility with Apple ecosystem devices or FiRa-certified solutions. Consider its low power consumption profile for battery-operated devices. Evaluate the need for dual-antenna PDoA support versus simpler ranging-only applications to determine if this specific feature set is necessary.

RF Transceiver ICS Part Context

The DW3120 series represents the next generation of Qorvo's UWB technology, succeeding the DW1000 series. It builds upon the foundation of the DWM3000 module family, offering improved performance and security. This integration allows for reduced external bill of materials and smaller solution footprints compared to previous generations.

RF Transceiver ICS Replacement Considerations

The DW3120 is backward compatible with Channel 5 operations of the DW1000. Designers migrating from DW1000-based solutions should verify software and hardware adaptations for the new IEEE 802.15.4z features and potential pinout differences inherent to the updated silicon generation.
