SI4432 long range wireless module 1500m (Surface mounted Device)

The SI4432 Long-Range Wireless Module (SMD) is a compact sub-GHz transceiver designed for reliable, low-power, long-distance communication. Operating across 240 MHz to 930 MHz, it supports programmable output power up to +20 dBm and excellent receiver sensitivity, enabling robust wireless links in varied environments. The module integrates a digital modem, packet handling engine, and efficient power-saving modes, making it ideal for embedded wireless applications requiring extended range and stable performance. It uses FSK, GFSK, and OOK modulation and features built-in TX/RX switching support and antenna-related enhancements to improve communication quality. Its low operating voltage, small SMD-friendly QFN package, and minimal external component requirements make it suitable for compact designs. Features: Wide operating frequency range: 240-930 MHz Programmable RF output power up to +20 dBm Very low active receive current Supports FSK, GFSK, and OOK modulation Integrated digital modem with packet handling Antenna diversity and switching support Operates from 1.8 V to 3.6 V Compact 20-pin QFN SMD package Package Includes: 1 x SI4432 long range wireless module1 x Helical Antenna
