Murata’s Type 2AB UWB Bluetooth modules are available from Rutronik
Small, wideband modules by Murata combine low power consumption and accurate results for compact, battery powered IoT devices.
The Type 2AB UWB + Bluetooth Low Energy wideband modules measure 10.5 x 8.3 x 1.44mm. They use short range radio frequency technology to enable a wide range of applications including healthcare, wearables, smart lighting, smart factory, real time locations systems (RTLS), asset tracking and digital payments.
The modules integrate a Nordic IC nRF52840 which is claimed to improve design flexibility and reduce product development time by eliminating external MCUs. There is a 256kbyte RAM and 1Mbyte flash memory, a 250nA deep sleep mode with Bluetooth Low Energy function and a three-axis sensor for motion detection. It also integrates a reference clock for UWB (ultra wideband) and MCU.
The module’s PCB mounting area is significantly reduced compared to the layout of separate UWB and BLE ICs, said Rutronik. The design also supports additional component integration. The regulatory-certified module is also claimed to minimise development time for adding UWB functionality into end products.
The multi-antenna design consists of three antenna ports available on the component, one for Bluetooth Low Energy and two for UWB for the phase difference of arrival (PDoA) function.
The connectivity module has an operating temperature of -40 to +85 degrees C and a voltage of 2.5 to 3.6V. It also supports channels five and nine for global deployment. Transmit power, antenna delays and frequencies are calibrated for each device.
