UWB module offers design flexibility with RF technology

Murata has launched the Type 2AB UWB + Bluetooth Low Energy, available now from Rutronik, one of the smallest ultra-wideband modules currently available (10.5mm x 8.3mm x 1.44mm). The combination of low power consumption and high accuracy with reliability produces an efficient and cost-effective variant for compact and battery powered IoT devices. The module employs short-range radio frequency technology to facilitate a wide range of applications. It is ideal for healthcare, wearables, smart lighting, smart factory, RTLS, asset tracking, and digital payments.

Its integrated Nordic IC nRF52840 provides improved design flexibility and shorter product development time by eradicating external MCUs, among other benefits. Also, there is 256kB RAM and 1MB flash memory, a 250nA deep sleep mode with BLE function, and a three-axis sensor for motion detection. A reference clock for UWB and MCU is integrated.

With this highly integrated module, PCB mounting area is notably decreased over a layout with separate UWB and BLE ICs, plus supporting further component integration. The development time for adding the UWB functionality into end products will also be reduced by employing this Regulatory Certified Module product.

The module offers developers flexibility due to a multi-antenna design. Three antenna ports are provided on the component – one for BLE and two for UWB for the PDoA function.

The connectivity module functions smoothly at a temperature range of -40C to 85C and a voltage of 2.5V to 3.6V. It also supports Channels 5 and 9 for global deployment. Transmit power, antenna delays, and frequencies are calibrated for every device.
