What is testbench for LNA

[ramesh441]

Can any one give the test bench for LNA differential topology (double ended)?????

I want to find ac gain response.

ramesh411,

go through the attached document showing Test bench for Diff LNA Simulation Let me know, is it meaningful to you or not ?

. could you tell me is there any need to plot ac gai response. for LNA you need to plot power gain and more RF advanced simulation.

Thanks for the reply,

I am having the material you have attached.

I want to find the ac gain response . I am not getting proper response with this testbench .This testbench is good for linearity analysis (1db, IIP3)

Is there any separate testbench for ac gain response.
