Abstract: Noise filtering is an essential part for measurement of quantum phenomena at extremely low temperatures. Here, we present the design of a filter which can be installed in space constrained cryogenic environment containing a large number of signal carrying lines. Our filters have a -3db point of 65kHz and its performance at GHz frequencies are comparable to the best available RF filters.
