Can you show me the bode plot of this circuit?

If you change the diode into something linear, i could make a plot for you. But let me first ask you why you need a plot to drive a LED?

Actually, I don't need the diode .I added it for my convenience.

I replace the diode to the resistance

ok, you propably know, a bode plot will compare input voltage with output voltage. See the capacitor at input. It will have no impact at all. Because the AC source is perfect with zero ohm internal resistance, and does not care about any load. Do you really want it that way, then you can remove the cap.

Thanks for your comment. I removed the cap

You still want this bode plot? Because now its just a low pass filter and not as in your headline BPF.

Here is a plot. Dotted line is phase shift http://i.imgur.com/2bp5z5v.png
