Ampwave Defense

Built to Perform

Ampwave Defense specializes in high-performance power tubes, traveling wave tubes, and microwave power modules — each engineered to precise frequency, power, and bandwidth requirements for applications that accept no compromise.

High-performance power tubes
From voltage regulators for airborne and fixed-station equipment to research, FM, VHF, UHF, and defense-grade transmitting tubes, our power tube lines deliver the output and RF amplification demanded by ballistic missile defense, broadcast, and advanced communications systems.
GO
Traveling wave tubes
Our traveling wave tubes power electronic countermeasures, radar, airborne military platforms, rack-mount amplifiers, and SatCom systems — engineered for the bandwidth, gain, and reliability these missions require.
GO
Microwave power modules
Our microwave power modules combine TWT performance with solid-state driver integration to meet the power, bandwidth, and spectral purity demands of today’s most advanced microwave systems.

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
