WAVEGUIDE SHORTS

General Description:

Series 380 waveguide shorting plates provide high reflection short circuits for terminating all standard waveguides from WR430 to WR28. They are designed to mate with the standard cover or choke flanges in each waveguide size. The units listed in the table are made of aluminum, but brass is available as as option.

WAVEGUIDE PRESSURE WINDOWS

General Description:

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. Impedance matching designs provide low VSWR performance in all of the standard waveguide sized from WR284 to WR28.

Material:

• Flange.....Brass
• Window......Copper-Clad, Teflon-Fiberglass
• Flange Type.....Cover Standard

Options:

• For cover/choke flange, add - 1
• For choke,choke flange, add -2
