Pressure Windows

RF Com have 3 types of Pressure Windows.

Glass reinforced PTFE windows and are suitable for pressures up to 40 psi.

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

Kapton windows are available for lower pressures and offer improved performance, typically better than 1.05:1 over the full waveguide bandwidth.

Quartz windows are available for very high power requirements (They are usually tailored to a customer’s particular requirements so please advise us of your specific requirements.)

The bodies can be made of brass or aluminium and various finishes can be applied. Standard windows have plain faces without a sealing groove and can be supplied to mate with most common flange outlines.

Our manufacturing facility is approved to ISO 9001: 2008.
