SiLSi4461-C2A-GMR
Overview
The Si4461-C2A-GMR is a high-performance, low-current ISM band transceiver part of Silicon Labs' EZRadioPRO family, covering the sub-GHz frequency range. It offers exceptional sensitivity of -116 dBm and output power up to +16 dBm, making it ideal for long-range wireless links. The device is designed for battery-powered applications with a low standby current of 40 uA and a shutdown current of 30 nA.
Why Choose This Part
The transceiver offers a wide operating voltage range from 1.8V to 3.8V and operates efficiently with a run current of 18 mA at +10 dBm output. Its high integration in a small 4x4 mm QFN20 package reduces external BOM count while providing superior blocking and selectivity for noisy RF environments.
Applications
Getting Started
Development is supported by the Wireless Starter Kit (WSTK) and Silicon Labs Simplicity Studio, which includes the Radio Configurator tool for optimizing PHY settings. Engineers should focus on the SPI interface for host MCU communication and utilize the WDS (Wireless Development Suite) for rapid prototyping of RF link parameters.
