DRF4432F27-043S is a type of low cost RF front-end transceiver module based on SI4432. It keeps all the advantages of RFIC SI4432 but simplifies the circuit design. The high sensitivity (-122dBm) and 27dBm output power make the module suitable for long range applications. DRF4432F27-043S module consists of RFIC SI4432, 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 is fully compatible with DRF4431F13 and DRF4432F20 modules.
