Detailed Product Description
SI4432 wireless module / SI4432-B1-FMR/470MHZ/433MHZ/915MHZ
SI4432 radio block / SI4432-B1-FMR is our long-distance data transmission is specially developed ultra-high-power and high sensitivity wireless module. SI4432 wireless chip operates at 240MHZ-960MHZ, can point applications, but also the composition of a star network, the module SI4432 data transmission module design operating frequency is 470MHZ, in the RF section, the Division has done a lot of debugging optimized to match, making the highest emission efficiency, harmonic minimal, making the SI4432 wireless module for RF interference external devices to achieve the lowest , while not susceptible to interference from other devices, greatly improve the stability of the work, the maximum transmitting power module is 19.6dbm, receiver sensitivity is-113dbm (9.6K rate test), measured with a spring-antenna distance of about 1000 meters, external 5DB columnar antenna distance can reach 1600 meters, pin spacing is 1.27mm, making more compact PCB design technology, providing MCS51 test procedures and test boards, and C8051F920 SI4432 and NRF24LE1 of test procedures, as well as the factory supplied EZMacPRo documents and related procedures, as well Si443X register set EXCEL documents, make simplified application SI4432
