Mica Rectangular Waveguide Pressure Windows

Space Machine offers a standard product line of mica pressure windows covering waveguide sizes WR28 thru WR284.
VSWR is 1.15:1 maximum, while insertion loss is 0.15dB maximum over the full waveguide bandwidth.
Pressure handling capability is 10 PSI maximum. Additional sizes and configurations are available upon request.
This window is well suited for high power and vacuum applications.
* Thickness noted when using a cover/cover flange configuration. When using a CPR or CMR flange type configuration, thickness is 0.25”. A choke flange face configuration requires a greater thickness.
