SX1278IMLTRT Integrated Circuit Chip IC Chip 137MHz To 525MHz Long Range Low Power Transceiver

The SX1278 transceiver features the LoRa® long-range modem, providing ultra-long-range spread-spectrum communication and high interference immunity while minimizing current consumption.

Using the patented LoRa modulation technique, the SX1278 achieves a sensitivity of over −148 dBm with a low-cost crystal and bill of materials. This high sensitivity, combined with the integrated +20 dBm power amplifier, yields an industry-leading link budget, making it optimal for any application requiring range or robustness. LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity, and energy consumption.
