Fundamental Principles and Design Elements of Double-Ridged Waveguide Magic Tee

• The Evolutionary Design of Ridged Waveguide Technology

The Double-Ridged Waveguide Magic Tee represents a significant advancement over conventional waveguide structures, incorporating specialized ridge elements that fundamentally transform its electromagnetic characteristics. These ridges—protruding metal structures that extend inward from opposite walls of the waveguide—create a unique electromagnetic environment that dramatically expands operational bandwidth while maintaining critical performance parameters. The dual-ridge structure is particularly significant as it creates a more complex electromagnetic field distribution compared to single-ridged or standard rectangular waveguides. This sophisticated design allows the Double-Ridged Waveguide Magic Tee to support multi-mode propagation while simultaneously minimizing higher-order mode interference, a critical factor in maintaining signal integrity across broader frequency ranges. Advanced Microwave Technologies Co., Ltd. has perfected this design through decades of research and development, producing Double-Ridged Waveguide Magic Tees that achieve exceptional bandwidth-to-size ratios while maintaining excellent power handling capabilities and impedance matching across the entire operational spectrum from 2 GHz to 110 GHz.
