Cutting-Edge mmWave Cabling Solutions

Millimeter-wave frequencies — defined as 30 GHz to 300 GHz — have moved from specialized defense and research applications into commercial volume production. 5G NR FR2 operates in the 24-47 GHz bands. Automotive radar systems use 77 GHz. Satellite communications are migrating to Q/V band (40-75 GHz). Each of these markets requires cable assemblies that maintain low, consistent insertion loss across the full operating band — and that survive the environmental and mechanical conditions of production test environments.\n\nJunkosha's mmWave cable assemblies address this market with the EMF series — precision ePTFE dielectric assemblies available in frequency variants from 26.5 GHz through the world-record 250 GHz MWX0A5. For 5G infrastructure testing, the EMF-01 and EMF-07 at 40-67 GHz provide the combination of phase stability and flex durability that production ATE systems require. For 77 GHz automotive radar characterization, the EMF-00 at 67-145 GHz covers the full band with low insertion loss and repeatable phase performance.\n\nProduction test environments subject cables to thousands of connection cycles. Junkosha's connector terminations are specified for defined mating cycle lifetimes, and the cable assemblies are qualified under repetitive flex conditions representative of ATE handler motion.\n\nKoto Electronics supplies Junkosha's full mmWave cable range in Israel, serving 5G chipset test, automotive radar, and satellite component manufacturers.
