For this LNA, I have two questions.

 

1. Does this filter outside should be loaded by ourselves?

 

2. If so, what's the frequency range.

 

3. If so, what's the purpose of this filter, is it used to filter harmonic noise created by LNA or is it used to work for us and give us the target frequency range our system need?

 

Thanks
