[Moon] Andrew Amplifier 2100-2200MHz

[DF6NA]

Hi Jerry,

just a little note to let you know that the amplifier is running on 2320MHz.
As I could not get any information on the first two stages I just run the
driver and final stage and get >20dB gain.

BTW: there is a little ic that measures drain current via a resistor.
It's a smd ic marked 'ADIU' - can't find information about that.

73, Rainer
