SI1021-B-GM2R

Product Overview

SI1021-B-GM2R is a sub-GHz ISM RF transceiver IC from Silicon Labs. It handles the RF transmit and receive functions needed for sub-GHz ISM wireless links. In a design or maintenance project, it is a candidate for sub-GHz ISM telemetry, remote control, metering, security and industrial wireless products.

Before design approval or replacement purchasing, check sub-GHz ISM-band options such as 315 / 433 / 470 / 868 / 915 MHz should be verified against the exact ordering code. The antenna network, protocol stack, firmware version, power profile, regulatory requirements and lifecycle status should be matched to the original design or target application.
