[hpsdr] Munin amplifier - 1st gain stage T5

[Laurence Barker]

Hi everyone

 

Does anyone know if the 1st gain stage (T5) on Munin has been tested, and
what its gain is please? The assembly instructions show all the components
for that stage as "do not insert" which I assume is because the
Penelope/Pennylane/Hermes boards all have 0.5W output and don't need that
stage.

 

I want to use Munin with a lower power red Pitaya TX which will have closer
to 1 milliwatt max output after going through a variable attenuator. I
assume I will need some kind of gain between it and the Munin even then -
bit does anyone have any measurements or results please?
