Junkosha is set to showcase its extensive range of high frequency cabling solutions at the IEEE MTT International Microwave Symposium (IMS) 2024, the premier annual gathering for microwave technologists. Making its debut is the new metrology-grade MWX871 cable, designed for specialized applications such as vector network analyzer (VNA) calibration tests, delivering the highest accuracy measurement for frequencies up to 70 GHz. Alongside this latest product, Junkosha will feature its ultra-phase stable cable line-up designed to meet the higher frequency demands of tomorrow’s 5G/6G networks.

With the widespread adoption of 5G and the transition to higher frequencies, the demand for mmWave-compatible cables in product R&D and shipment inspections is increasing. Depending on the degree of degradation and the characteristics of the cable itself, the signal amplitude frequency characteristics of these cables can fluctuate when bent leading to measurement errors and decreased stability. In response to these challenges, Junkosha has developed the new 70 GHz metrology-grade microwave/mmWave VNA Test Cable which offers exceptional phase (within +/- 8.9 degrees) and amplitude stability (within +/-0.10 dB) during flexure, along with robust phase stability in varying temperatures.

Tomohiro Ogawa, product manager at Junkosha, explains: "Developed in-house, the key dielectric components in Junkosha’s mmWave cables are optimized for peak performance. Consequently, the cable exhibits outstanding phase stability and phase-return characteristics, as well as its resilience to bending and temperature fluctuations. Equipped with a ruggedized port-side NMD connector for reliable and robust connections to the VNA, this new interconnect solution is designed to withstand the most demanding testing environments."

With over 70 years of industry-leading experience in the RF market, Junkosha offers an extensive range of test cables tailored for various Test & Measurement applications. Their product portfolio includes high phase stability cables for measuring instruments up to 145 GHz, cables designed for wide temperature ranges and high durability for product verification up to 67 GHz and EPTFE tape wrapped phase stable cables for testing integrated antenna systems up to 67 GHz.
