SX1276IMLTRT

SX1276IMLTRT is the tape-and-reel order code for the Semtech SX1276, a long-range LoRa transceiver covering 137 MHz to 1020 MHz in a QFN-28 package, listed by Semtech as Pb-free and RoHS/WEEE compliant. It integrates a +20 dBm power amplifier, down to -148 dBm receiver sensitivity and up to 168 dB maximum link budget, supports LoRa plus FSK, GFSK, MSK, GMSK and OOK modulation, and draws 9.9 mA in receive through an SPI interface with a 256-byte packet engine. Selection advice: frequency coverage is the hard divider inside this family - the SX1276 spans the full 137 MHz to 1020 MHz range while the SX1278 variant stops at 525 MHz for allocations such as the China 470 MHz to 510 MHz metering band, so the two are not interchangeable in a band-specific design; also match the code character-for-character, because the similarly spelled SX1276TIMLTRT was covered by a Semtech end-of-life notice and is a different part.
