nRF24L01+ RFX2401C

[simof]

Hi all,

I would like to realize my PCB module with nRF24L01+ and RFX2401C PA/LNA.
My idea is to use a PCB antenna but I didn't have any experence in that means.

Someone can explane me how i have to realize the filter and the pcb antenna?
Are there some example in Altium Designer format?

Thanks

Hi,

 
I do not think we have Altium Designer format for nRF24L01+, but you can look at the HW in the gerbers here: nRF24L01+_Radio_Module_PCB_Antanna.zip

The layout is also shown in the Product Specification: infocenter.nordicsemi.com/.../nrf24L01p_ps.html

 

The RFX2401C must be placed between C6 and the antenna, follow the requirements and suggestions  from the manufacturer as closely as possible.

 

You can either copy the antenna in the design above or you can design it as you like. This whitepaper describes the design: https://infocenter.nordicsemi.com/pdf/nwp_008.pdf?cp=12_18 

Also note that you need to tune the antenna: https://infocenter.nordicsemi.com/pdf/nwp_017.pdf?cp=12_11 

 

Another alternative is to use a 3rd party or SMD antenna. Follow the instructions from the manufacturer or designer as closely as possible.

 

Best regards,

Andreas
