Module SI4432 digital module design working frequency is 470 MHZ, the rf part, reached the highest emission efficiency harmonic minimum, make the SI4432 radio module to the outside equipment of radio frequency interference to a minimum, at the same time, it is not susceptible to interference from other equipment, greatly improve the stability of the work. The maximum transmission power module in 19.6 DBM, receiving sensitivity of 113 DBM for rate test (9.6 K), measured with spring antenna distance is about 1000 meters, an external 5 db cylindrical antenna distance can reach 1600 meters, pin spacing is 1.27 mm, make the PCB design is smaller.
