3 Introduction
The DA14580 QFN48 antenna module is based on the Dialog Semiconductor DA14580 Bluetooth
®
Smart SoC. It is a stand-alone system consisting of the DA14580 SoC in a QFN48 package, 16 MHz
and 32 kHz crystals, a DC/DC converter and a printed antenna. The module was successfully tested
for FCC/IC certification and CE marking. This document presents the module system, its technical
specifications, physical dimensions and test results.
