A Secure Source of Critical RF Power — Today and for Decades to Come

Many of the systems our products support will remain in service for decades. Ampwave Defense exists to make sure the tubes inside them never become the weak link. With a manufacturing heritage dating to 1942, U.S.-based production in Lancaster, Pennsylvania, and ownership committed to long-term investment in vacuum electron device technology, we provide program managers and sustainment teams something rare in this industry: certainty of supply.

  • Continued production of legacy and heritage tube designs
  • Form-fit-function replacements for obsolete devices
  • Build-to-print and engineered-to-specification programs
  • U.S. manufacturing with full quality traceability
