Description

EasyEDA project for easy and quick build LNA module. Project include schematic for LNA module and PCB's with differences in the power circuit and Bias Tee implementation (PCB with/without reverse polarity protection circuit, PCB with/without TCBT-14+ Bias Tee module). Version for mounting SMD components.

Current development progress:
