VSWR Gating

VSWR was plotted by averaging the data of 10 mates. Data collected was gated from .125” into the cable and .125” into the board trace as illustrated. See Figure 1.

Figure 2

Insertion loss was tested as a thru measurement on two FeatherMate connectors to four 2.92mm Ø.047 6” FleXtra® cable assemblies joined via a test PCB. FeatherMate connectors were mated and demated 10 times by hand to generate the results shown. See Figure 2.

FeatherMate Assembly ProcessStep 1:

• Select and mount the appropriate hardware set for the intended board (see page 4)

Step 2:

• After placing the bushings on the bottom side of the board, from the top torque the provided single .063” hex socket screw in each bushing (solder-free operation)

Note: the internal diameter of one of the bushings is larger than the other to prohibit mismating and to provide the keying feature of the FeatherMate

Step 3:

• Tighten the FeatherMate cable assembly block .050” hex socket screws into both bushingsThe compression of the center contact spring pin and the flexure of the cantilever beam grounding element store the potential energy in the contact system to maintain consistent normal force for the signal path
