Murata has launched the world's smallest ultra-wideband module (UWB), measuring just 10.5mm × 8.3mm × 1.44mm. The module offers a high level of accuracy and reliability with low power consumption, ensuring efficient battery-powered operation, which is a key factor in the design of IoT devices.

Utilizing short-range radio frequency (RF) technology, the 2AB UWB + Bluetooth Low Energy (BLE) connectivity module can be used in a wide variety of applications where precision sensing is essential. These include social distancing applications in the workplace to minimize the spread of COVID-19.

 
 

The system-in-package module includes three antennas: two UWB for Phased Difference of Arrival (PDoA) and one for BLE. The high positioning accuracy of the module and extensive safety functions make it particularly suitable for sectors such as healthcare, wearables, industry, smart home and consumer electronics. 2AB facilitates asset tracking, indoor navigation, smart lighting control, digital payments, and location applications such as proximity tag search. It is equally well suited for use in smart factories, POIs, hospitals, museums, warehouses and underground structures. The UWB module offers significant advantages over Wi-Fi, Bluetooth or GPS based systems, noting that the latter is unsuitable for indoor use due to its dependence on satellite signals.

Compared to other chip-on-board designs, the UWB module containing Qorvo integrated circuits enables a reduction in mounting space of approximately 75%. Other advantages of the Surface Mount Module include an embedded MCU from Nordic Semiconductor with embedded BLE, eliminating the need for an external MCU. Additional features include memory (256 KB RAM and 1 Mb Flash), a 3-axis motion sensor, 250 nA deep sleep mode, and the ability to operate in temperatures from -40 ° C to 85 ° C with a voltage from 2.5 V to 3.6 V.

'We forecast that the UWB market will grow by around 30% in the coming years and will be driven by the growing sectors of smartphones, IoT and smart cities,' comments Toshifumi Oida, Senior Director of Communication Modules at Murata. 'Our ultra-compact, highly reliable 2AB module with excellent EMI performance is an attractive solution for product developers looking to serve this market with breakthrough high-density RF assembly technology.'
