2000 Milliwatts si4463 PA Module, 433/868/915Mhz
N4542AS module based Silicon Labs si4463 FSK transceiver wireless chip, pa, the module designed for 433M/490M/ 868M/ 915Mhz Sub G band. N542AS can be program register for customizer. The N542AS module has +33 dBm output power and the sensitivity down to -126 dBm at 1.2 kbps. The module support long distance data broadcast and thread.
The SI4463 module has a small SMD package, Integrated SI4463 and pa and IPEX, it reduced a lot of development troubles.
N542AS module hardware is designed for maximum range, 13000m + Range (Low rate and Line of Sight).
