DRF4432F27 is also based on SI4431/SI4432 from Silicon labs. The -122dBm sensitivity and 27dBm output power make the module suitable for long range applications. DRF4432F27 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. Users can design products with suitable modules and easily replace them with other family modules in the future when applications have different requirements on distance.
