• DC–110 GHz operation with ≥1,000 mating cycles
Product overview
VST-TWS90J-08 is a DC–110 GHz vertical PCB multi-port RF connector integrating eight independent 50 Ω signal paths in a compact 1×8 configuration. Its 2.54 mm contact pitch supports high-density board-level interconnection for multi-channel RF and mmWave test systems. A screw-retained stiffener provides mechanical support for the connector assembly during PCB installation.
