Representative RF performance & configuration

The datasheet provides representative TW70 series RF measurements from a different configuration (reference: VST-L-TW70MF116-300), including S14 transmission and S11/S44 reflection responses. These series-reference results are not presented as measurements of this 1×4 female-ended assembly.

For ordering, specify cable length, port-to-channel mapping, TW70 mating interface and RF requirements. A configuration-specific RF test report is supplied with each delivered assembly.
