Global interconnect pioneers, Junkosha, have unveiled their latest Microwave/mmWave Coaxial Cable Assembly solution at this year’s European Microwave Week (EuMW 2025) capable of transmitting from DC to 250 GHz. As the first solution of its kind, the new 0.5 mm connector cable “MWX0A5” represents a unique capability in the marketplace, placing Junkosha at the forefront of high-frequency cable innovation for the demands of probe stations and test setups for advanced chips, especially those designed for AI accelerators.
Developed from a blank slate collaboration with Keysight Technologies, MWX0A5 is engineered to meet the needs of engineers working at the limits of high-frequency testing for applications including semiconductor devices in AI-related chip characterization and emerging THz research. While no device under test (DUT) currently features a 0.5 mm interface, Junkosha’s latest 250 GHz interconnect lays the foundation for the next generation of millimeter wave measurement systems at the heart of the future’s highly sophisticated systems.
“As AI data centers grow and demand more bandwidth, testing at higher frequencies becomes essential,” said David Tanaka, Product Manager at Keysight. “Together with Junkosha, we are able to deliver the required test accessories for broadband, sub-THz measurements.”
Tomohiro Ogawa, Product Manager for Junkosha adds: “Unmatched by any other cable or waveguide currently on the market, the cable maintains excellent return loss across the full frequency range up to 250 GHz ensuring minimal signal reflection and superior transmission performance. Thanks to the benefit of Junkosha’s cabling which features a PTFE tape dielectric layer, this cable is equipped with features including low insertion loss only reaching about –7 dB at 250 GHz, as well as a proprietary safety-lock connector for secure and repeatable connections.”
Junkosha will be exhibiting the MWX0A5 cable alongside its comprehensive portfolio of cable solutions at European Microwave Week (EuMW 2025) in Utrecht at Booth F053 from the 23rd to 25th September. Now in its 28th year, the annual European Microwave Exhibition, which is by far the largest RF and microwave trade show in Europe, is held in conjunction with a wide range of relevant conferences. The exhibition also includes a series of technical seminars and exhibitor workshops describing commercial products and processes.
