PIN photodiode wideband LNA DC-2GHz

lna 2ghz

Hello,
For a PIN photodiode, I've to design a wideband LNA from low freg (+-1Mhz) to 2GHz. The gain have to be 40dB, NF ideally at 3dB.
I think that I've all the theoretical background to do this but since I've no experience with such frequencies I'm looking for advice, schematics,...
Is anyone could help me?
Regards,

Probably your thesis adviser .

Is it so difficult?
With two transistor stages it can be done, no?
BTW, i'm not a student! ;-)

Depends on sensitivity you want to reach. If that is not a big issue, you could teminate the photodiode in a resistor and amplifiy with a broadband amplifier type minicircuits or so.

That's what I concluded after a Google search. I'll use some ready made modules. There are several manufacturer and it's cheap.
Thanks
