BS EN 61580-9:1997

What is BS EN 61580-9- Rectangular waveguide interfaces about? 

BS EN 61580-9 is the ninth part of an international standard that provides the methods of measurement for waveguides. 

BS EN 61580-9 gives the means for determining the reflection coefficient at the junction of two 

similar rectangular waveguides due to the following imperfections: 

• Differences in the waveguide internal dimensions 
• The lateral displacement between the waveguide axes in either the H or E plane 
• Angular misalignment between the waveguide axes 

BS EN 61580-9 helps in determining the reflection coefficient. 

Who is BS EN 61580-9- Rectangular waveguide interfaces for?  

BS EN 61580-9 on rectangular waveguide interfaces is relevant to: 

• Manufacturers of the communication equipment 
• Manufacturers of fibre optic devices 
• Manufacturers of optical fibre 
• Fibre optic technicians 
• Fibre optic installers 
• Electromagnetic engineers 
• Communications engineers 
• Testing authorities 

Why should you use BS EN 61580-9- Rectangular waveguide interfaces? 

Rectangular waveguides are extensively used in radars, couplers, isolators, and attenuators for signal transmission. Due to tolerances in waveguide dimensions, flange alignment holes, and bolt diameters, the junction between two similar waveguides can give rise to reflections of an input signal.  

BS EN 61580-9 examines the effects on reflection coefficient due to the various tolerances. The users can determine the effect of dimensional changes and axial displacement for small changes in reflection co-efficient. It also contributes to investigating angular misalignment between waveguide flanges caused due to tolerances in rectangular waveguide interfaces. 

Overall, BS EN 61580-9 provides guidance on the methods of measurement for waveguides and the reflection coefficient in rectangular waveguide interfaces that can be beneficial for your business.
