New 0.5 psec Skew Matching Cables Up to 250 GHz

Differential signal integrity at extreme frequencies demands sub-picosecond timing precision. Junkosha's latest skew-matched cable assemblies — the MWX001, MWX002, and flagship MWX0A5 — achieve 0.5 psec skew matching across pairs, enabling clean differential measurement up to 120 GHz and single-ended transmission to 250 GHz.\n\nSkew mismatch is one of the leading sources of eye closure in high-speed serial measurements. When cables introduce differential delay, the resulting jitter and inter-symbol interference corrupt waveform analysis and mask device performance. The new MWX series eliminates this variable by factory-matching pairs to within half a picosecond — tighter than any competitor offering at these frequencies.\n\nThe MWX0A5 breaks new ground as the world's first coaxial cable assembly to cover DC through 250 GHz. Built around a 0.5 mm connector developed in collaboration with Keysight Technologies, it enables sub-THz characterization of next-generation semiconductor devices, AI accelerator chips, and advanced packaging interconnects. Insertion loss at 250 GHz is approximately 7 dB — a benchmark performance figure at this frequency.\n\nAll three assemblies are built on Junkosha's ePTFE dielectric technology, delivering thermal phase stability and mechanical flex durability alongside the skew-matching specification. Standard lengths and custom lengths are available. Inquire through Koto Electronics for pricing and availability in Israel.
