SI4432 1000 Meters Long Distance Wireless Module

Silicon Laboratories’ Si4432/31/30 highly-integrated, single chip wireless ISM transceiver is part of the EZRadioPROTM family. The EZRadioPRO family includes a complete line of transmitters, receivers, and transceivers allowing the RF system designer to choose the optimal wireless part for their application.
The Si4432/31 offers advanced radio features, including continuous frequency coverage from 240–930 MHz and adjustable output power of up to +20 dBm with the Si4432. The Si4430 offers frequency coverage from 900 to 960 MHz to support the Japanese frequency bands. The Si4432/31/30’s high level of integration offers reduced BOM cost while simplifying overall system design. The extremely low receive sensitivity (–118 dBm) coupled with the Si4432’s industry- leading +20 dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance. Antenna diversity is completely integrated into the Si443x and can improve the system link budget by 8–10 dB, resulting in substantial range increases under adverse environmental conditions.
