Hello,
I'm trying to tune the matching circuit of the PN5180.
EMVCo L1 reception test is failing and needs to be resolved.
In the received waveform, the balance between Ich and Qch seems to be unbalanced in the long-distance test.
How can I tune the matching circuit (impedance) to control this IQ balance?
(Currently it matches 20Ω, the RxGain is MAX.)
Thank you !
You mean "Your weakness is not the IQ balance. It may be spike noise." , right?
Hello @s04 .

Hope it help you.
Have a nice day.
