SX1261IMLTRT Product Details

Semtech’s SX1261IMLTRT and SX1262 are sub-GHz radio transceivers that support LoRa modulation for LPWAN (low power wide-area network) and (G)FSK (Gaussian frequency shift keying) modulation. The transceivers are highly configurable to meet different applications utilizing the global LoRaWAN™ standard and comply with the physical layer requirements of the LoRaWAN specification released by the LoRa Alliance™.The devices are designed for long-range wireless applications and support long battery life. The SX1261IMLTRT can transmit up to +15 dBm and SX1262 can transmit up to +22 dBm with highly efficient integrated power amplifiers. The radio is suitable for systems targeting compliance with radio regulations including but not limited to ETSI EN 300 220, FCC CFR 47 Part 15, China regulatory requirements, and the Japanese ARIB T-108. Continuous frequency coverage from 150 MHz to 960 MHz allows the support of all major sub-GHz ISM bands around the world.<strong>Features:</strong> 170 dB maximum link budget, Low RX current of 4.6 mA, Integrated DC-DC converter and LDO, Programmable bit rate up to 62.5 kbps LoRa and 300 kbps FSK, High sensitivity: down to -148 dBm, 88 dB blocking immunity at 1 MHz offset, Co-channel rejection of 19 dB in LoRa mode, Built-in bit synchronizer for clock recovery, Asset tracking, Smart meters, Supply chain and logistics, Building automation, Smart cities, Retail store sensors, Street lights, Healthcare, Sensors for safety, security, environmental, and agricultural
