DRF4431F27-086S module consists of RFIC Si4431, thin SMD crystal, LDO and PA circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don’t need to spend time in RF circuit design. It keeps all the advantages of RFIC SI4431 but simplifies the circuit design. The high sensitivity (-122dBm) and 27dBm output power make the module suitable for long range applications. It is compatible with 868MHz DRF4431F13-086S and DRF4432F20-086s modules in communication.
