1/ Dimensions are in inches.
2/ Metric equivalents are given for general information only and are based upon 1.00 inch = 25.4 mm.
3/ Flange in accordance with MIL-DTL-3922.
4/ Connector shall be female type N (corrosion-resistant steel). Shock, vibration, and salt spray
requirements are not required for this Part or Identifying Number (PIN).
5/ A larger attenuator pad may be used for VSWR test setup (see figure 1 of MIL-DTL-22641) when
measuring VSWR values less than 1.25:1.
6/ Swept frequency measuring technique is an acceptable alternate test method for determining VSWR
and RF insertion loss value.
7/ Waveguide in accordance with MIL-DTL-85.
8/ Reduced height waveguides and flanges.
