Pressure Windows
CPI EDB manufactures and tests a wide variety of vacuum and pressure windows currently used in: space / satellite; lab testing; and radar applications. CPI is able to manufacture pressure windows for high--volume applications or design fully custom one-off windows to meet your project’s needs. CPI features these pressure window materials:
- Tef-glass: Great VSWR performance over full bandwidth; ideally used in low-power and low-pressure applications
- Glass: Hermetic glass to metal sealed windows; great for low loss, vacuum and medium power applications
- Quartz: Great for high-power (5+ KW of CW power) and high-pressure or vacuum applications; very low insertion loss windows and good VSWR performance over a wide variety of frequency ranges
- Ceramic: Very high power-handling capabilities (10+ KW of CW power); can be liquid cooled or have cooling fins added to window to aid in prolonged high power operation
Though most of CPI EDB's windows are made with Glass, Quartz, Ceramic, or Tef-glass, ask about custom pressure window materials. CPI BMD can manufacture windows in waveguide sizes of WR10 to WR1000, including half-height configurations.
