Hermetic SMP / SMPM RF Feedthroughs

Hermetically Sealed

Precision hermetic RF feedthroughs in SMP and SMPM  formats, engineered for high-frequency, space-constrained applications. Constructed entirely from Kovar (both body and pins), these components offer unmatched hermetic sealing, thermal stability, and RF performance for mission-critical systems. 

  • RF Performance
    SMP up to ~18 GHz
    SMPM up to ~65 GHz
  • Miniature Format
    Designed for high-density layouts and lightweight RF modules.
