Waveguide Windows: Design Overview and Capabilities
For the best possible performance, we recommend that your microwave feed system be maintained under a slight positive pressure. This helps to prevent the entrance of moisture or other contaminants. In our design of waveguide windows, we utilize the newest dielectric materials to ensure high power capabilities and optimum functionality.
A general overview of our designs, and expanding capabilities for waveguide windows includes:
- Gas barriers
- Block windows
- Vacuum windows
- Pressure windows
- Window assemblies
- Ultra high vacuum windows
- A variety of materials available
- Available with or without gas ports
- Ability to incorporate water cooling
- Various flange and interface options
- Supporting sizes from WR90 to WR2300
Most units are less than 1.00″ (25.4 mm) thick in WR650 to WR975, and 2.00″ (50.8 mm) in WR1150 to WR2300.
Applications and Use Cases
Waveguide windows are used in many microwave and RF applications, especially those in which waveguide systems are present. Common applications include: gas discharge and power tubes, sealing the antenna systems, resonant cavities, and ferrite components. Our windows reach end users in a variety of cutting-edge applications and fields, including:
- Laboratory RF testing
- Military radar systems
- Antenna feed networks
- Satelitte communications
- RF combining applications
- High energy physics research
- Radiation oncology equipment
About Waveguide Windows
What are waveguide windows?
They are a type of seal, for use in microwave and RF applications, as a measure of preventing contaminants from entering a waveguide system. Examples of contaminants include: moisture, dirt, and dust. These devices allow a signal to pass through, while at the same time, blocking atmospheric gasses or contaminants from passing through the system.
What is their main purpose?
In addition to keeping contaminants out, waveguide windows may help to isolate pressurized sections of a waveguide from non-pressurized sections in a system. They can also be used to seal waveguides when pressurization or inert gas filling is required. In addition, they may help with increasing power handling capabilities within a waveguide system. Depending on the window type, material, and application, they may have different objectives.
What are common window material types?
Various materials are used in the fabrication and assembly of waveguide windows. Depending on the application, windows may incorporate: alumina, quartz, rexolite teflon, sapphire, PTFE, ceramics, OFHC copper, and others.
