10dB attenuator

The attunator that is shown here has a damping of 10dB that means it turns the 30mW output of the BS11 into 3mW output. Please note that 10dB is only an example. The attenuator is designed to be configured to any damping factor.

The first thing you should do is calculating the resistor values here:

Resistors values can be calculated at:
http://www.aroesner.homepage.t-online.de/d-glied.html

The values you get will not match to the resistor values you can by. That is the reason why the PCB has 3 resistors in series to form one of the resistors you have calculated with the script.
