LoRa radio module simplifies wireless design and supply-chain management for IoT

Murata has unveiled its groundbreaking Type 2GT module, a multi-band LoRa module that marks a notable leap forward in the development of IoT devices needing versatile wireless connectivity. This highly integrated module stands out by providing a comprehensive solution that caters to the complex demands of global certification standards, enabling seamless deployment in diverse regions and industries.

The Type 2GT module is 9.98mm x 8.7mm x 1.74mm and is built on a PCB housed in a metal case and packaged as a land grid array. The module’s technical prowess is highlighted by its use of Semtech’s advanced LR1121 RF transceiver IC, a TCXO, a second 32KHz crystal, an RF switch, and an RF matching network. These components ensure maximum frequency accuracy and reliable performance under varying environmental conditions. For end-device designers, this translates to simpler and small-sized PCB designs, decreased time to market, and lower development costs, thanks to the module’s ease of integration and streamlined certification process.

The module’s support for multiple frequency bands – including sub-GHz bands, the 2.4GHz ISM band, and the 2.1GHz satellite communications S-band – underscores flexibility and scalability, meeting the necessities of various IoT applications such as smart agriculture, industrial and environmental sensing, building and home automation. Other markets which could benefit from the module’s features include asset tracking, utilities metering, remote-controlled toys and drones. Support for the 2.4GHz ISM band enables higher data rates and common channel plans across the globe and also allows designers to avoid the duty-cycle limitations imposed on sub-GHz communications by European standards.

“We are thrilled to witness Murata’s strategic expansion with their cutting-edge, third-generation multi-band LoRa modules,” said Carlo Tinella, senior product marketing manager at Semtech. “This advancement provides the industry with a pivotal tool to streamline and secure the development process for applications operating across sub-GHz and 2.4GHz LoRa frequencies. Murata’s commitment to reducing design complexity and certification challenges empowers developers worldwide, enabling swift and versatile IoT solutions for everything from smart agriculture to urban infrastructure.”

The company module is certified to European CE and American FCC standards, the Japanese TELEC standard, and the Canadian IC standard, permitting designers to reuse module RF test reports across different certification authorities. This will greatly lower compliance barriers, fostering innovation across the IoT ecosystem to serve users in multiple geographies.
