How to design ultrawideband amplifier (UWB LNA) using TWA?

Hi guys...
Sorry to disturd u all... i just want to ask something about uwb lna using TWA. I need to do project on it with spec "to build an amplifier with a bandwidth in excess of 5GHz using filtronic InP pHEMTs".Could u plss tell me the steps on desingning TWA .. Any of u have any idea? Ur kindness on helping me is appreciate...

Regards, SHah

Dear friends,

Sorry to disturb u...I just got the specification on this amplifier
- to build an amplifier with a bandwidth in excess of 5GHz using filtronic InP pHEMTs
-The gain is 10dB +/- 0.1dB
-S11 and S12 below 15 dB
Input and Out put Impedance shoulbe be 50 ohm..
I just wondering what is the best circuit eg using TWA,cascode, feedback etc to provide the best result for the amplifier ? Hopefully u all can help me on doing this project.
