SX1261, SX1262 and SX1268 sub-GHz radio transceivers are ideal for long range wireless applications. Both devices are designed for long battery life with just 4.2 mA of active receive current consumption. The SX1261 can transmit up to +15 dBm and the SX1262 and SX1268 can transmit up to +22 dBm with highly efficient integrated power amplifiers.

Features :

  • LoRa and FSK Modem
  • 170 dB maximum link budget (SX1262 / 68)
  • +22 dBm or +15 dBm high efficiency PA
  • 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
  • FSK, GFSK, MSK, GMSK and LoRa modulation
  • Built-in bit synchronizer for clock recovery
  • Automatic Channel Activity Detection (CAD) with ultra-fast AFC
