DRF4431F13 is a type of low cost RF front-end transceiver module based on SI4431 from Silicon labs. It keeps all the advantages of RFIC SI4431 but simplifies the circuit design. The high sensitivity (-121dBm) and 13dBm output power make the module suitable for most short range applications.
Features:
* 433MHz transceiver
* 13dBm output power
* -121dBm sensitivity
* Standard SPI interface
* Temperature sensor and 8-bit ADC
* Standby current: <1uA
* Data Rate: 0.123~256 kbps
* Supply voltage: 1.8~3.6V
Application:
* Remote Control
* Remote AMR
* Home Automation
* Personal data logger
* Wireless sensor network
* Remote Keyless entry
* Wireless PC peripherals
DRF4431F13 module consists of RFIC Si4431, thin SMD crystal and antenna matching circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don't need to spend time in RF circuit design and choose suitable antennas for different applications. DRF4431F13 operates at 1.8~3.6V with extra low standby current which makes it suitable for battery powered-up applications. DORJI also provides high power si4431 module DRF4431F27-086S with 500mW output power in 868MHz band and DRF4432F27 in 433MHz band, which provides users high flexible in designing products for different distances.
