Microwave flexible cable, 1 m / 3.1 ft, DC to 40 GHz, 2.9 mm female K to female 3.5 mm connector

PSMCUFB142A      CAD36  US$28

Flexible COAX cable, bends easily, minimum bend radius 9.65 mm / 0.38"
Center conductor solid silver plated copper, 0.2 mm / 0.08" dia
Outer conductor silver plated copper braid, 3.61 mm / 0.142" dia
Dielectric: Ultra Low Density PTFE
Manufacturer says: For applications greater than 26.5 GHz but less than 40 GHz and when lower loss is required, choose this cable. A version with 7 strand center conductor allows even more flexibility.
While 40 GHz is specified as maximum frequency manufacturer recomends use below that, see previous line.
Finding a suitable male 2.92 mm K connector reaching up to 40 GHz will be  impossible because of cable diameter at 3.61 mm, no practical way to use this more flexible cable at 40 GHz! Next, many connectors are available with cable purchase only and are not offered as standalone parts.

Why use semi-rigid cable?
