PNEV5180 : Connecting it to an external Antenna

[harpoon]

Hi all,

I am trying to figure out how I can connect the PN5180 (using the PNEV5180 development board) to and external amplifier, and then to an antenna.

The details :-

I have the EMVCo test bench with a tuned antenna (like a Poller-0 antenna) and wish to use the PNEV5180 to communicate with a card using this antenna.

While I have some ideas on how to wire up the TX, I am not too sure about the RX path back to the PNEV5180

Can someone provide some insights ?

Thanks.

Yes， you may cut the OM25180 along the red line shown as below, and add the amplifier between these two parts.

Please note the matching circuit should be adjusted.

Hope that helps,

Have a great day,
Kan
