Overview

The Si4463-C2A-GM is a high-performance, low-current transciever from the EZRadioPRO family, covering the sub-GHz frequency range from 142MHz to 1.05GHz. It is designed for long-range wireless applications, offering up to +20dBm output power and an exceptional sensitivity of -129dBm.

Why Choose This Part

This transceiver offers a high level of flexibility with support for GFSK, 4GFSK, GMSK, and OOK modulations at data rates up to 1Mbps. It features advanced radio functions like Automatic Gain Control (AGC) and Automatic Frequency Control (AFC) to maintain link stability, while maintaining a low shutdown current of 30nA.

Applications

Smart Metering
Optimized for automated meter reading (AMR) systems requiring high link budgets and reliable industrial performance.
Wireless Alarm Systems
Used in security and home automation sensors for long-range connectivity and low standby power consumption.
Industrial Remote Control
Ideal for heavy machinery control and site monitoring in environments where 2.4GHz interference is problematic.
Asset Tracking
Supports LPWAN implementations for tracking assets across large industrial sites using sub-GHz propagation.
