SX1262 Main Features

• LoRa-dat® and FSK-dat modulation
• 150 MHz to 960 MHz frequency range
• High sensitivity: down to -148 dBm
• +22 dBm maximum transmit power
• Low current consumption: 4.2 mA RX, 28 mA TX @ +14 dBm
• Integrated TCXO == crystal-dat
• Small size: 4x4 mm QFN package
• Suitable for long-range IoT applications
• Compliant with LoRaWAN® and IEEE 802.15.4g standards
• Automatic Frequency Control (AFC)
• Time-of-Flight (ToF) capabilities
• Built-in antenna switch
• Digital RSSI == RSSI-dat
• Packet engine to perform CRC, FEC, whitening, and address filtering

Core Frequency Range

The chip supports a continuous range from 150 MHz to 960 MHz.

While the silicon itself can tune to any frequency in this range, actual hardware modules (like those from Electrodragon.com) are typically optimized for specific regional bands using specialized RF matching circuits.

Summary:

• The SX1262 generally offers better performance in terms of power consumption, sensitivity, and size, and supports a wider frequency range and IEEE 802.15.4g. It's a newer generation chip.
• The SX1278 is an older, more established chip that is still suitable for many LoRa applications, particularly where cost is a primary concern and the advanced features of the SX1262 are not required.
