[Skimmertalk] T14 Transformers

[Martin Rath]

Hi,

I have just scanned the description of the LNA by DC2PD :
https://drive.google.com/open?id=1GDQZ0YOuEy983Z9HiQ2QuuRlPqBlq4n2

It has a 60 MHz Low pass filter as well as an attenuation that is
controlled throught the I2C bus of the Red Pitaya and Pavel's image.
