LR1121IMLTRT
SemtechLR1121IMLTRT is a multi-band LoRa transceiver from Semtech in a QFN-32 5x5 mm package, supporting sub-GHz operation from 150 MHz to 960 MHz plus the 2.4 GHz band and L/S satellite bands, with LoRa, (G)FSK, LR-FHSS and Sigfox modulation, up to +22 dBm transmit power on sub-GHz, -141 dBm sensitivity and an SPI host interface; Semtech lists the product status as Active. One radio covering terrestrial sub-GHz, global 2.4 GHz and satellite bands lets a single hardware design serve worldwide tracking and logistics applications without regional variants, simplifying certification, stocking and firmware maintenance. Selection advice: pick LR1121IMLTRT when the product must roam across regions or combine ground and satellite connectivity; if only one sub-GHz band is needed, a simpler device such as LLCC68 cuts cost and design effort, and antenna design needs care because the bands span a very wide frequency range. Parameters verified against Semtech documentation.
