Hi,
On DA14585 daughterboard, you mounted just 2 components for impedance matching. What is the values of them ? I viewed your design files, 1.4 pF capacitor and 4.7 nH inductor used. however, another inductor did not determine . Do they provide good matching ?
Thanks,
Device:
Hi uprozarif,
Could you please indicate which inductor you mean? Please check out theAN-B-027: Designing Printed Antennas for Bluetooth Smartapplication note. In this document you will find all the available guidelines you need for designing printed antennas. The DXF files are available to :AN-B-027: Designing Printed Antennas: DXF files.
Thanks, PM_Dialog
I am asking rf matching components.
Can i copy to your db design for custom board. Could you share which components u used, also share rf trace and layer stack measurements ?
Thanks.
Hi uprozarif,
Yes, you can take as a reference and use it in your design. In our support portal, you will find all the HW collaterals (schematics/ layout / BOM)
