SX1276 in Semtech SX12xx LoRa Family
The SX1276 is a flagship long-range transceiver family from Semtech Corporation, utilizing LoRa spread spectrum technology alongside traditional FSK/OOK modulation. Operating across the 137 MHz to 1.02 GHz frequency range, these devices are engineered for high interference immunity and exceptionally long-range communication at low power. They serve as a cornerstone for LPWAN infrastructure, enabling connectivity in environments where standard wireless protocols fail due to range or obstruction constraints.

Comparing specs that differ across variants.
| Part Number | Frequency | Package | RF Family/Standard | Rx Current | Tx Current | Stock |
|---|---|---|---|---|---|---|
| SX1276IMLTRT (Semtech Corporation) | 137M | VQFN-28 | 802.15.4 | 10.8mA | 20mA | 43,095 |
| SX1276MB1LAS (Semtech Corporation) | 433M | Module | 1GHz | 12mA | 120mA | 15 |
Variants in the SX1276 family primarily differ in their packaging and hardware integration levels. The IMLTRT suffix denotes the bare silicon IC in a VQFN lead-frame package for high-volume PCB integration. Other variants, such as the MB1LAS, are pre-certified evaluation modules or reference designs that include necessary front-end matching circuitry and SMA connectors, simplifying the RF design path for rapid prototyping.
