DW3120SB

RF Transceiver ICS Overview

The Qorvo DW3120SB is a second-generation fully integrated pulse radio ultra-wideband (UWB) transceiver IC based on the IEEE 802.15.4z standard. It supports UWB channels 5 (6.5 GHz) and 9 (8 GHz), offering data rates of 850 kbps and 6.8 Mbps. The device features two antenna ports enabling Phase Difference of Arrival (PDoA) for angle measurement with accuracy under 5 degrees, while ranging precision remains below 10 cm. Operating on a supply voltage of 2.4 to 3.6 V, it includes AES security functions and is compatible with Apple U1 chips.

RF Transceiver ICS Feature Summary

• Supports IEEE 802.15.4a and 802.15.4z BPRF standards with enhanced security features
• Dual antenna ports enable precise Angle of Arrival (AoA) measurements via PDoA
• Compatible with Apple U1 chip ecosystem for interoperable location-based experiences
• Optimized for low-power battery-supplied operations with minimal external BOM

RF Transceiver ICS Applications

• Smart manufacturing and industrial IoT real-time locating systems
• Consumer electronics digital keys and access control
• Precision indoor positioning and asset tracking
• Secure ranging and authentication protocols

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'SB' against official Qorvo documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges (-40°C to +85°C). Confirm that design-in requires an external microcontroller as the DW3120 does not include an integrated MCU. Validate antenna matching networks for Channels 5 and 9 to maintain specified performance metrics.

RF Transceiver ICS Selection Notes

Select the DW3120SB when dual-antenna support for AoA is required alongside high-speed data transmission up to 6.8 Mbps. It serves as a direct upgrade path from single-channel devices like the DW1000, offering backward compatibility on Channel 5. Consider this component for applications demanding sub-10 cm ranging accuracy and strict adherence to FiRa™ certification standards for secure consumer interactions.

RF Transceiver ICS Part Context

The DW3120SB belongs to Qorvo’s second-generation DW3000 series UWB transceivers, succeeding the first-generation DW1000. This family targets mobile, consumer, and industrial markets by optimizing for low power consumption and small form factors. The series enables global UWB support through multi-channel operation and integrates advanced security protocols to meet evolving industry requirements for precision location services.

RF Transceiver ICS Replacement Considerations

The DW3120SB is backward compatible with the DW1000 on Channel 5. For single-channel applications requiring similar functionality, consider the DW3110. If higher integration or different package constraints are needed, evaluate the DW3210 or DW3220 variants within the same generation family.
