Product overview

VST-L-TW90MF108-XXXX is an 8-channel TW90 multi-coaxial breakout cable assembly that transitions a compact, single-row multiport interface to eight individual 1.0 mm male coaxial connectors. Designed for 50 Ω RF and millimeter-wave interconnects through 110 GHz, it enables grouped signal paths to connect to separate measurement instrument or test-fixture ports.
