Detailed description

The SX1276/77/78 transceivers are mainly based on LoRaTM remote modems for ultra long-range spread spectrum communication with high immunity to interference and minimize current consumption. With the patented LoRaTM patented modulation technology, the SX1276/77/78 achieves high sensitivity of over -148dBm with low cost crystals and materials. In addition, the high sensitivity and +20dBm power amplifier integration makes these devices' industry-leading levellink budgets the best choice for long-haul transmission and reliability-critical applications. Compared with the traditional modulation technology, LoRaTM modulation technology also has obvious advantages in anti-blocking and selectivity, which solves the problem that the traditional design scheme can not balance the distance, anti-interference and power consumption at the same time.


These devices also support high-performance (G)FSK modes for systems such as WM-Bus and IEEE802.15.4g. Compared with similar devices, the SX1276/77/78 significantly optimizes phase noise, selectivity, receiver linearity, and third-order input intercept point (IIP3) Variousper formance based on a significant reduction in current consumption.
