Here is the question: if I want to switch AC and (AC+DC) signal from a
high speed op-amp, the output load is 50 ohm, I want to put a
capacitor between op-amp output and the 49.9 ohm resistor, how to
choose the capacitance?

thanks.


What is the minimum & maximum frequency? If you want DC you can't
use a capacitor. In that case, use a split +/- supply and reference the
op amp to ground.
