8-Port Ganged SMPM to 1.85mm Male Cable Assembly DC–67 GHz VST-L-TW70MF108

P/N: VST-L-TW70MF108-XXXX

  • For high-density multi-port RF interconnects
  • Ganged 8-channel format for faster test setup
  • Tight phase matching for repeatable multi-port measurements
  • Well suited to ATE and 6G mmWave platforms
  • Supports applications through 67 GHz
Engineering Note
VST-L-TW70MF108 is an 8-port ganged SMPM to 1.85mm male cable assembly for compact high-density microwave interconnects. It is specified for 50 Ω systems and supports DC to 67 GHz operation, with return loss ≥ 13 dB, insertion loss ≤ 11.55/1000 × L + 1.3 dB, and phase matching ±2 ps. The 1×8 channel format is suited to dense test fixtures and parallel RF paths where compact port grouping and controlled channel consistency are required.

Target Applications

Compact Multiport Test Systems
Suitable for dense multi-channel fixtures where a ganged SMPM interface reduces footprint while maintaining individually routed high-frequency channels.
Parallel RF Signal Routing
Used where multiple matched RF paths are required between compact board-side SMPM interfaces and precision 1.85mm test connectors.
Millimeter-Wave Validation Platforms
Appropriate for 67 GHz validation environments where channel density, phase consistency, and compact cable management are required.
