RTS4438 high performance wireless FSK transceiver module, Based on Silicon Labs SI4438 RTS4438 of wireless transceiver chip design, it is a compact, low power consumption Long-distance wireless transceiver module. Silicon Labs introduced this chip is mainly set to 433MHz, 470MHz, 510MH other countries to network-specific bands, the sensitivity can be achieved -121dbm, the maximum transfer rate up to 500Kbps, the output power range -20dbm register configuration to + 20dbm. Module integrates all RF related functions, users do not need in-depth understanding of RF circuit design, you can use this module to easily develop a stable performance, high reliability wireless products, shorten product development cycles. Module uses a single-chip architecture, the external high-precision crystal, high-Q inductors Murata and small volume high-capacity filter capacitor. All using SMD components, interface with standard pitch stamp edge package, which will help the development compact system patches and batch applications.


  • Wireless sensor 1800 m transmission distance (1200bps).
  • Home automation operating frequency 433.92M (other frequencies to be customized).
  • Automated data collection Operating voltage: 1.8V-3.6V.
