MIL-DTL-3933 (M3933) RF Attenuators
MIL-DTL-3933 United States Military Detail Specification covers fixed attenuators intended for use in military
equipment systems and space systems such as satellite payloads. These attenuators are commonly found in
testing and measurement equipment, some circuits, and most applications requiring the power reduction of a
signal without distorting its waveform. M3933 attenuators are available in a wide range of frequency bandwidths
and decibels of relative power.
MIL-DTL-3933 includes three device level designations indicated by the last character of the part number: (T) part
numbers denotes use in space applications, (S) screened and (N) non-screened part numbers are intended for all
other applications. Both the screened and non-screened part numbers are tested for Standing Wave Ratio
(SWR), attenuation, and peak power. The screened components are tested against additional trials including but
not limited to thermal shock, conditioning, and radiographics.
