SI4461 Description

Short technical summary and product information.

The Silicon Labs SI4461 is a high-performance, low-current transceiver IC designed for sub-GHz frequency bands, covering the range from 119 to 1050 MHz. As part of the EZRadioPRO family, it provides outstanding receive sensitivity of -126 dBm and supports a maximum output power of +16 dBm.

 

This device features flexible modulation options including (G)FSK, 4(G)FSK, (G)MSK, and OOK. It operates with a power supply range of 1.8 to 3.6 V and exhibits low active current consumption, with RX at 10 mA and TX at 18 mA (+10 dBm). Ultra-low powerdown modes include 30 nA shutdown and 50 nA standby, ensuring extended battery life.

 

The SI4461 boasts excellent selectivity performance with 60 dB adjacent channel selectivity and 75 dB blocking at 1 MHz. It is compliant with IEEE 802.15.4g and meets various worldwide regulatory standards such as FCC and ETSI. The device is supplied in a compact 20-pin QFN package, suitable for space-constrained applications.
