Introduction

The RF4438PRO module is based on the Silicon Labs si4438 C device, a highly integrated wireless ISM-band transceiver IC. The exceptionally low receive sensitivity of -124 dBm, combined with industry-leading +20 dBm output power, ensures extended range and improved link performance. Built-in antenna diversity and frequency hopping support further enhance range and performance. The RF4438PRO is manufactured and tested using a strictly lead-free process, compliant with RoHS and REACH standards.
