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:

Progress Progress Bug report

List of changes:

Version 2.0.EE: changes of the toggle switch (SW1) on the printed circuit board, now the contacts of the case are soldered to the GND area. The RF line width has been recalculated using Saturn PCB Design V7.08. At the moment, the wave resistance of the RF line is close to 50 Ohms. Correcting a power-up error due to PCB trace in module LNA (SMD): Main module (simplified DC connector). PCB Implementation Fix for LNA (SMD): Main module (BT only).
