Product Bulletins

CPI's Beverly Microwave Division (CPI BMD) is a designer and manufacturer of pulsed ring-loop traveling wave tubes operating in the L-, S-, C- and X-Band frequency ranges. Typical peak power levels offered range from 1 kW to 15 kW, with duty cycle capability up to 6 percent.

Small and lightweight products for pulsed radar and most advanced designs for commercial, electronic warfare and radar systems are included in this CPI BMD product line.

The unique ring-loop slow-wave structure used in these CPI BMD traveling wave tubes provides high gain at kilowatt peak RF power levels without oscillation and achieve greater than 30% efficiency.

All of CPI’s high-power pulsed traveling wave tubes are metal-ceramic structures that provide exceptional reliability under the most adverse conditions encountered in aircraft, shipboard and missile environments.
