IFA matching circuit components

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,

Hi uprozarif,

Hi uprozarif,

Could you please indicate which inductor you mean? Please check out the AN-B-027: Designing Printed Antennas for Bluetooth Smart application 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.
