S2-LPQTR
Overview
The S2-LPQTR is a high-performance, ultra-low power sub-1GHz RF transceiver designed for long-range wireless applications. It supports multiple modulation schemes including 2GFSK, 4GFSK, ASK, and OOK, and is specifically optimized for Sigfox and Wireless M-Bus protocols. With a sensitivity of -130dBm and a maximum output power of 10dBm, it provides a robust link budget for low-power wide-area networks.
Why Choose This Part
The S2-LPQTR offers industry-leading power efficiency with a 7mA RX and 10mA TX current, extending battery life in field deployments. It features a built-in CSMA/CA engine and automatic packet acknowledgment to offload protocol handling from the host MCU. Its wide supply voltage range of 1.8V to 3.6V supports a variety of battery chemistries without complex regulation.
Applications
Key Specifications
Getting Started
Engineers can evaluate the transceiver using the X-NUCLEO-S2868A2 expansion board paired with an STM32 Nucleo development platform. ST provides the STSW-S2LP-DK software package, which includes drivers and a graphical user interface for RF configuration and testing. Hardware design is simplified by the 24-VFQFN package and a minimal bill of materials for the matching network.
