The RF4463PRO module uses the Silicon Labs Si4463 device, a highly integrated wireless ISM band transceiver chip. Its extremely low receive sensitivity (-126dBm), coupled with industry-leading +20dBm output power, ensures extended range and improved link performance. Meanwhile, built-in antenna versatility and frequency hopping support can be used to further extend range and improve performance. Sensitivity up to -126dBm Maximum output power: 20dBm 10mA@receive status Data transmission rate: 0.1-1000kbps (G)FSK, 4(G)FSK, (G)MSK, OOK and ASK1 modulation modes Ultra-low power-off mode Digital Received Signal Strength Indicator (RSSI) Timed wake-up function Automatic antenna matching and bidirectional switch control Configurable packet structure Preamble detection 64/128-byte transmit/receive data register (FIFO) Low power detection Temperature sensor and 8-bit analog-to-digital converter Integrated voltage regulator Frequency hopping function Power-on reset function Built-in crystal adjustment function 1.8-3.6 V power supply Operating temperature range: -40-+85 Applications: Remote control Remote meter reading Industrial control Home automation telemetry Toy control Wireless PC peripherals Tag reader/writer.
