Si4432 is one of EZRadioPRO series launched by Silicon Labs in 2009. It is a highly integrated wireless ISM transceiver chip, which can work in 240-960 MHZ band range with very high receiver sensitivity (-121dBm) and maximum output power up to +20dBm. Under the condition of high-power setting, it can make the communication distance in open surrounding reach thousands of meters.
The module integrates all RF related functions and hardware. Users can easily develop wireless related products with stable and reliable performance without any knowledge of radio.
