DA1469x Radio Antenna


I was looking through the DA1469x series datasheet, specifically in regards to the Radio architecture. I would like to know if the antenna connected to the RFIO pin is already on the chip or if the Radio schematic suggests that an antenna be connected to it separately. Please let me know.

Thank you

Hi sgutala,

Hi sgutala,

Thanks for your question online and for your interest in our DA1469x series. Please checkout out the AN-B-066: Hardware Design Guidelines application note and see section 5.14 RFIO Port. Also refer to AN-B-027: Designing Printed Antennas for Bluetooth Smart for designing printed antennas. The DXF files are available to AN-B-027: Designing Printed Antennas: DXF files .

Thanks, PM_Dialog
