Passive attenuator

thingiverse

This is a box which is taylor made for a resistive matching attenuator. Just mount two BNC connectors through the holes in the box and wire them with 3 resistors. There are many calculators out there which provide you with the values needed in order to give a specific attenuation and impedance. As it is advisable to shield the attenuator you will also find a part which you can use as a gauge to draw the outline on a piece of copper sheet. This copper can be folded inside the box. Typically the 3 resistors will be soldered to form a Pi-attenuator, but this really is up to you. Finally the L-shaped lid has to be glued onto the box.
