Junkosha Microwave/mmWave Coaxial Cable Assembly
As the industry’s first test cable assembly capable of stable signal transmission up to 250 GHz, the new 0.5 mm connector cable “MWX0A5” features a robust 0.5 mm NMD female connector and is designed for high-frequency measurement environments that require precision, stability, and reliability. Developed in collaboration with Keysight Technologies, it is an ideal solution for applications such as semiconductor devices in AI-related chip characterization and sub-THz research, supporting transmission from DC to 250 GHz. Its low insertion loss—achieved through a custom dielectric layer—and excellent return loss maintain signal quality even at the upper limits of the frequency band.
A 0.5 mm–1.0 mm adapter will be available for compatibility with common DUT interfaces.
