RF4432X1 443MHz Embedded Wireless Transceiver Module For Remote Control Smart Home

Item Overview: The RF4432X1 module uses the Silicon Lab Si4432 device, a highly integrated wireless ISM band transceiver chip. Extremely low receive sensitivity (-121 dBm) combined with industry-leading output power of 20 dBm, guarantees extended range and improved link performance. At the same time, built-in antenna diversity and support for frequency hopping can be used to further expand the range and improve performance. Specifications: Frequency range: 433MHz Power supply: 1.8-3.6 V Operating temperature range: -40 ~ 85 C Sensitivity: up to -121dBm Maximum output power: 20dBm (30mA@ 13dBm) Data transfer rate: 0.123-256kbps (FSK, GFSK, OOK mode) Features: - Ultra low power shutdown mode and digital receive signal strength indicator (RSSI) - With timer wake-up function, frequency hopping function, power-on reset function and built-in crystal adjustment function - Antenna automatic matching and bidirectional switch control - configurable packet structure - 64-byte Transceiver Data Register (FIFO) - Low energy detection and pre-sync signal detection and temperature sensing - with 8-bit analog-to-digital converter and integrated voltage regulator Technical Parameters: Parameter Minimum Typical maximum Unit Condition Operating conditions Operating Voltage 1.8 3.3 3.6 V Operating temperature -40 85 Current consumption Receiving current 18.5 mA Emission current 85 mA @20dBm Sleep current < 1 uA RF parameters Frequency Range 403 433 463 MHZ @433MHz 838 868 898 MHZ @868MHz Modulation rate 0.123 256 Kbps FSK Transmit power 1 20 dBm Receiving sensitivity -121 dBm @data=1.2kbps Application: - remote control - Remote meter reading - Home security alarm and remote keyless entry - Industrial control Package Included: 1 x Wireless Transceiver Module
