About Our Waveguide Flanges

What is a Waveguide Flange?

A waveguide flange is a crucial component used in microwave and radio frequency (RF) systems to ensure seamless and secure connections between sections of waveguide tubing. These specialized flanges facilitate the efficient transfer of electromagnetic waves through waveguide assemblies without significant power loss. Designed to match the specific size and mode of the waveguide, these flanges not only ensure a precise fit but also maintain the integrity of the signal transmission, crucial for high-frequency communications. By providing a mechanical means to connect and disconnect waveguide sections, they allow for flexibility in system design and maintenance, ensuring reliability and performance in a variety of settings.

Customization Options for Microwave Flange

At RALLY, we understand that the requirements for waveguide flanges can vary widely depending on the application. That's why we offer extensive customization options to ensure that our products perfectly match your specifications. Below, we detail the materials, machining process, and customizable features available for our waveguide flanges.


Our waveguide flanges are available in two primary materials, each with its unique advantages:

  • Brass Flanges: Brass is renowned for its excellent machining properties, corrosion resistance, and good conductivity. Brass flanges are ideal for applications where durability and a lower cost are prioritized. They are particularly suitable for indoor environments where the material's natural corrosion resistance can ensure longevity and consistent performance.

  • Aluminum Flanges: Aluminum stands out for its light weight, excellent conductivity, and corrosion resistance. These flanges are perfect for applications where weight is a critical factor, such as aerospace and mobile systems. Aluminum also exhibits good thermal conductivity, making it suitable for high-frequency applications where heat dissipation is essential.
