Recently I have been interested in a digital rf stepped attenuator project .I was wondering if anyone had tried to use two of these boards to increase the maximum attenuation given to the input signal.One board alone yields a maximum of 31.5 db of attenuation.For most applications this would be sufficient.Is it possible to connect two in series to increase the maximum attenuation to 63 db ?The project can be viewed on YouTube if you put in diy rf digital attenuator as a search.
