Designed for next generation probe systems, the Junkosha Microwave/mmWave Coaxial Cable Assembly MWX009 supports accurate and repeatable measurements at 167 GHz and beyond

Booth number: 21025
Interconnect pioneers, Junkosha, have announced the launch of their latest cable solution at this year’s IEEE International MTT Symposia (IMS). The new MWX009 Microwave/mmWave Coaxial Cable Assembly has been developed to support a wider range of probe system applications as the industry transitions toward higher-frequency testing infrastructure. Designed to meet growing market demand for advanced probe system measurements, the MWX009 cable is compatible with 0.5 mm and 0.8 mm connector interfaces, addressing evolving requirements in high-frequency test environments.

As demand for data bandwidth drives communication research into the D-band, systems require specialized D-band probe stations and vector network analyzers (VNAs) capable of characterizing channel behavior and antenna modules at extremely high frequencies. As such, engineers are seeking cable solutions that maintain signal integrity for higher-frequency probe setups beyond the widely adopted 145 GHz, that can reliably provide accurate measurements for testing and validation.

The MWX009 is positioned as a response to this shift, supporting emerging 0.5 mm and 0.8 mm interface requirements and enabling operation up to 190 GHz and 167 GHz respectively. The cable offers low insertion loss performance and excellent return loss; a key differentiator that provides superior electrical performance enabled by Junkosha’s custom expanded PTFE dielectric layer technology. It also features a secure safety-lock connector for improved connection stability. For sub-THz communication research and development pushing toward higher frequencies, the new cable will support engineers to access frequency ranges beyond 145 GHz.

“The massive bandwidths available in this range are crucial for future technologies, but they create strict measurement and testing challenges” explains Tomohiro Ogawa, Product Manager for Junkosha. “Without equipment that can reliably enable efficient and accurate measurement, comprehensive research and testing and validation becomes more difficult and time-consuming. This launch represents Junkosha’s strategic role in enabling technologies for advanced mmWave in near maximum frequency D-band measurement environments.”
In addition to the MWX009, the company will also be showcasing its MWX0A5 cable. Developed in collaboration with Keysight Technologies, it maintains excellent return loss across the full frequency range up to 250 GHz, ensuring minimal signal reflection and superior transmission performance. The MWX0A5 achieves low insertion loss reaching –7 dB at 250 GHz for a 6-inch (152 mm) length, as well as a proprietary safety-lock connector for secure and repeatable connections.

Junkosha will be showcasing its MWX009 and MWX0A5 at the IEEE International MTT Symposia (IMS) exhibition from June 7th-12th.
