Hi,
I am disign a LNA circuit, the parameters of it is good enough for my goal when pre-simulation and post-simulation without PAD.
But when I add the PADS to the circuit layout, the post-simulation results become bad, the |S11| decreased 1.5 dB and |S22| decreased 8dB when in High frequency, it made my circuit work badly.
Is there any PAD structure can fit the RF usage, please?
Thank you!
Best regards!
