Description

EasyEDA project for easy and quick build "LNA, Bias Tee powered" module for amplify weak radio signals without significantly increasing the noise level and compensation for loss of useful signal when passing through a coaxial cable. Project includes schematic and PCB prepared for setting up into aluminum enclosure with dimensions 50 x 25 x 25 mm with N-Type connectors. Version for mounting SMD components.
