Waveguide Pressure Windows

Pressure Windows

The Waveguide Solution pressure windows incorporate a seal of glass reinforced PTFE or quartz depending on the power requirement. All windows are pressure tested to 40 psi. The bodies can be made of brass or aluminium. Various Finishes can be applied (see ordering instructions). Standard windows have plain faces without a sealing groove and can be supplied to mate with most common flange outlines. Windows for standard rectangular waveguide sizes have a VSWR better than 1.10:1 over the full waveguide bandwidth, or 1.05:1 over a 50% bandwidth.

Double Ridge sizes have a VSWR better than 1.10:1 over an octave bandwidth, or 1.15:1 over the full frequency band. The Waveguide Solution facility is approved to ISO 9001: 2000.


	Very high power requirements are usually tailored to a customer’s particular requirements - please contact the factory for details
