Waveguide Filter

The device which is used to pass and to stop certain frequencies in the hollow metal pipes known as waveguide is called waveguide filter.

It is designed to be interfaced with waveguide based systems.

The figure depicts waveguide filter with various screw posts required for tuning to obtain the best performance as needed.

Following parameters should be considered before selecting waveguide filter:
• Frequency Range
• Bandwidth
• Number of Sections
• Power Handling
• Dimension as per waveguide size
• Configuration: single components or diplexed
• Interface:Waveguide flange or connectorized type
