Product Attributes

Introduction

Three module variants in different package sizes have been developed — RF4432PRO, RF4432, and RF4432X1 — to meet diverse customer requirements. All three modules feature an ultra-low receiver sensitivity of -121 dBm, combined with +20 dBm output power to ensure extended range and improved link performance. This series of modules is manufactured and tested strictly using lead-free processes, compliant with RoHS and REACH standards. Additionally, the RF4432PRO offers a CE-certified version to address varying customer product requirements. Customers can reference this certification during their system-level certification process, significantly saving time and reducing costs.
