Product overview

VST-L-TW70MF108-XXXX is an eight-channel multi-coaxial breakout cable assembly connecting a TW70 multiport interface to eight 1.85 mm male connectors. Designed for DC–67 GHz operation with 50 Ω impedance, it supports multi-channel RF and millimeter-wave test interconnections where cable routing and channel-to-channel timing consistency are important.
