Hi.

We need to design a custom board for LoRa 923MHz network.

I have read the AN5457 provides the example for 923MHz network. (A.1.6)

But I can't find RF Power Amplifier Impedance & LNA (Differential) Input Impedance for UFQFPN48 package @923MHz.

Could you please give me those data of this package and this frequency?

Thanks
