Attenuation range: 1 - 50 dB (see list of parameters in schematic file);
RF connector: SMA;
Feed line: 50 Ohm coaxial cable;
Used PCB Material: FR-4;
PCB thickness: 1.6 mm;
PCB copper weight: 1 oz;

List of changes:

Version 4.0.EE: removed old versions of PCBs due to the bulkiness of the end device in the case of their use. In this case, it would be much more optimal to use ready-made SMA attenuators.
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.
