Introduction

LLCC68SXXXN0SA series wireless module is a compact, low-power, long-distance two-way wireless transceiver module. The module adopts a high-precision active temperature-compensated crystal oscillator, which has better temperature stability than ordinary passive crystal oscillator modules, and the operating frequency offset is almost not affected by changes in ambient temperature, making it the best choice for wireless solutions in complex and harsh industrial environments.

The LLCC68 sub - GHz wireless transceiver is ideal for long-range wireless applications. It has a built-in high-efficiency power amplifier up to +22 dBm; the module can support LoRa modulation for LPWAN use cases and (G)FSK modulation for traditional use cases, with highly configurable parameters to meet different application requirements for industrial and consumer use. The LoRa modulation method is compatible with the technical specifications published by the LoRa Alliance. This wireless module is suitable for systems that comply with radio regulations, including but not limited to ETSI EN 300 220, FCC CFR 47 Part 15, Chinese regulatory requirements and Japan ARIB T-108. The wireless transceiver supports continuous frequency coverage from 150 MHz to 960 MHz, allowing it to support all major sub - GHz ISM bands worldwide.

The module integrates all RF-related functions and devices. Users can use this module to easily develop wireless solutions and wireless IoT devices with stable performance and high reliability without in-depth understanding of RF circuit design.
