The Silicon Laboratories SI4464-B1B-FM is a versatile RF transceiver IC designed for high-performance, low-current applications. It covers the sub-GHz frequency bands from 119 to 1050 MHz, making it suitable for a wide range of wireless communication systems.
Key electrical specifications include an outstanding receive sensitivity of -126 dBm and a maximum output power of +20 dBm. The device supports various modulation schemes such as (G)FSK, 4(G)FSK, (G)MSK, and OOK. It operates with a power supply range of 1.8V to 3.6V and consumes low current, with RX current at 10/13 mA and TX current at 18 mA at +10 dBm. Standby and shutdown currents are extremely low at 50 nA and 30 nA, respectively, ensuring extended battery life.
The transceiver boasts excellent selectivity performance with 60 dB adjacent channel selectivity and 75 dB blocking at 1 MHz, ensuring robust operation in challenging RF conditions. It supports data rates from 100 bps to 1 Mbps and features SPI serial interfaces.
Packaged in a 20-VFQFN Exposed Pad (20-QFN 4x4), this component is designed for surface mounting. The operating temperature range is -40°C to 85°C.
