Catalogue values support selection. Final tolerances, assembly performance and acceptance tests are defined in the approved drawing and specification. No certification is implied.
Stranded-centre-conductor microwave cables for routing that requires greater flexibility. Four sizes balance attenuation, mass and bend radius.

Typical attenuation at +25 °C and sea level. Repeated-flex acceptance requires an agreed bend radius, cycle method, frequency and phase/loss limits. No universal cycle-life rating is stated here.
Impedance: 50 Ω | All listed models
Cutoff frequency: 18 GHz | Listed cable models
Operating temperature: −55 to +125 °C | Finished cable
