Waveguide Pressure Windows

Series 235 pressure windows are designed to isolate pressurized sections from non-pressurized sections in waveguide systems. They are also used to prevent solid or liquid contaminants from entering the waveguide system. The material and sealing techniques employed insure high pressurization levels in the severe environments encountered in military applications. Impendance matching designs provide low VSWR performance in all of the standard waveguide sizes from WR284 to WR28.
