The company will also feature its novel “Cable Assembly Designer” tool to address the challenges associated with designing modern cable assemblies alongside its wider digital cable solutions

IMS booth number: 665

June 12th, 2025: Global interconnect pioneers Junkosha have chosen the world's largest gathering of the RF and microwave community, IMS 2025, to announce its MWX161 cabling solution as the ideal cable for connecting with multiport Vector Network Analyzers (VNAs) where space is at a premium. Alongside the MWX161, Junkosha will also announce the expansion of its Cable Assembly Designer; a product selection tool for Junkosha® Microwave/mmWave Coaxial Cable Assemblies that are customizable to a host of test and measurement, space and defense applications and high-frequency needs within mobile communication technology.

Junkosha’s MWX161 interconnect has excellent phase and amplitude stability over flexure and temperature change, is available with skew matching within 1 psec and performs up to 67 GHz. It is a highly flexible armored cable, so even when connecting to dozens of ports on a multiport VNA, the bending force generated when the cable is bent does not transfer to the device under test (DUT), allowing for stable measurements. Typical use cases, in addition to multiport VNAs, include testing signal integrity on printed circuit boards (PCBs); narrow pitch RF matrix switchers that route RF signals between multiple inputs and multiple outputs; and connector DUT boards which serve as an interface circuit between the automatic test equipment and the DUT. To add to its ease of connection, a torque driver is now provided to mount the interconnect on to the narrow pitch connector arrangement board or on to the VNA’s side.

“Today’s engineers are tasked with delivering the performance and reliability demanded by target applications while addressing growing demand for faster and more accurate test solutions,” explains Tomohiro Ogawa, Product Manager for Junkosha. “This is why at IMS we have our widest range of cabling solutions on show, including Junkosha MWX001 and MWX002 cables with new flexible armor and skew matching options. In addition, we will have our MWX004 cable available for viewing, which is the world’s first 145GHz flexible coaxial cable, and is equipped with features including advanced phase stability and the highest performing dielectric material.”

Selecting cables and connectors for a device under test setup can be a complex process resulting in a significant investment in time and money. Cable design is often the last challenge considered when developing a test system. However, it needs care and expertise because superior quality cabling is critical for accurate measurement. Unless the test engineer is a cabling expert, researching wires and connectors can be daunting. Therefore, Junkosha’s Cable Assembly Designer has become a valuable tool for test engineers designing cables for functional test systems.

“At Junkosha, we are constantly innovating next-generation cabling solutions that feature ultra-low dielectric loss materials, precision connectors, and armour options designed for durability,” explains Ogawa. “Each cable is designed to provide the highest reliability for testing and calibration purposes. The rise in demand requirements for projects that need higher quality and resilient interconnects means that the Cable Assembly Designer hasn’t simply been ‘bolted on’ to the website, but has been developed as a ‘support infrastructure’ that fully integrates with Junkosha’s existing ordering and manufacturing processes.”

At this year’s IMS, Junkosha is providing visitors information around a wide range of its innovative cable assembly solutions. For over 70 years, IMS has brought together a unique mix of international RF and microwave experts presenting the latest research and showcasing the newest products and services. IMS includes education and networking opportunities as well as an exhibition. The event is being held at the Moscone Center, San Francisco from 15th to 20th June.
