Hi,

we are looking for a bandpass filter with Q-Factor about 10000 for the
central frequency near 10 GHz.

Unfortunately the best offer we got till now is Q-factor about 3000.

Any idea where can we ask for the device?

Yes, look for waveguide-bandpass filter. They have very high Q-factors.

have a look at www.db6nt.de
They have lots of microwave stuff. Maybe you can discover something
there, if not, try to contact them. IIRC not everything they have is
on their web page.
