Description

EasyEDA project for easy and quick build "PI Attenuator" module for weakening too strong signals during receiving process. Project includes schematic and PCB prepared for setting up into aluminum enclosure with dimensions 50 x 25 x 25 mm with N-Type or SMA connectors. Version for mounting SMD components.

Current development progress:

Progress Progress Bug report

Maximum power dissipation: 300 mW / 24.77 dBm (for SMD 0805);
Attenuation range: 1 - 50 dB (see list of parameters in schematic file);
RF connector: SMA / N-Type;
Feed line: 50 Ohm coaxial cable;
Used PCB Material: FR-4;
PCB thickness: 1.6 mm;
PCB copper weight: 1 oz;

Not intended for use in the transmission path.

List of changes:

Version 3.0.EE: added versions of PCBs with the possibility of installation in an aluminum enclosure with dimensions of 50 x 25 x 25 mm.
Version 2.0.EE: the RF line width has been recalculated using Saturn PCB Design V7.08. At the moment, the resistance of the RF line is close to 50 Ohms.
