About Waveguide Flanges
What are waveguide flanges?
Put simply, flanges are connectors for joining sections of waveguides.
What is their main purpose?
Waveguide flanges are primarily used for connection purposes. To ensure minimal losses, flange types must match.
What shapes of waveguide flanges are there?
Primarily, flanges are rectangular, square, round, or circular.
What usually holds them together?
Flanges are usually held together with bolts to keep the connection tight.
What applications are they used in?
Flanges are utilized in various applications, such as: defense, scientific, medical, industrial, broadcast, and more.
How to Connect Waveguide Flanges in 5 Steps
Use the number sequence and tighten each bolt to create a uniform pressure on the connection.
- Begin applying hand pressure only.
- Apply minimal torque to take up any openings between the flanges.
- Take the torque to half the recommended level.
- Apply the full rated torque to the waveguide flange bolts.
- Repeat the tightening sequence at the full torque to verify.
Waveguide Flanges: Factors to Consider
When researching, designing, or procuring waveguide flanges, you will want to consider the following design factors:
- Flange type
- Insertion loss
- Pressurization
- Waveguide size
- Bolt hole pattern
- VSWR performance
- Operating frequency
- Machining tolerances
- Use of gaskets and O-rings
In allowing us to find a best fit solution for your application or system, obtaining the above information is key.
