I have a 13CM Spectrian amplifier board which I believe is about 60 watts output this is the board with the three LDMOS devices.
The one thing that I can’t find is the connection details. I have tried using Google lot of pictures but no real useful information that I have found.
Could some tell me the following info?
DC Power connections.
Bias connection and bias voltage and what to set the bias current too.
RF drive level.
There is also a small 10 pin header again is there any useful information i.e. fwd /ref power or temp?
Any pointers or links to find the information would be most welcome.
