ADA8282 LNA+PGA have 4ch input and output, in it's evaluation board they used some capacitor and resistor that just make question, the bandwidth of this amplifier is 10MHz min and 42MHz typ.
Can you analyze these and exactly say why are these here? the input and out put are differential.

Hi
The AD8282 operates on either single ended or differential I/O. P1INx and P1OUTx are used for I/O configuration and the inputs and outputs are typically AC coupled. For the output circuit of the evaluation board, those RC components are included for high pass filtering of the output.
Attached below is a typical application circuit for the part.
Best regards,
