The MWX002 from Junkosha is a 110 GHz cable that can be used up to 120 GHz when used with the optional Enhanced 1.0 mm connector. The cable is matched to 50 ohms has a propagation delay of 4.2 ns, has a wavelength reduction rate of 79% and a VSWR of 1.197:1 with a loss of 14.5 dB/meter at 120 GHz. Even when the cable bends 90-degrees the phase changes minimally throughout the entire process - this is before the cable is bent, while it is bent and after it is unbent.
