Rectangular To Circular Waveguide Transition

Achieves low-loss, low-reflection conversion between rectangular waveguide TE₁₀ and circular waveguide TE₁₁, effectively suppresses higher-order modes, ensuring signal purity and stable transmission.

Rectangular to circular waveguide transition serves as a key bridge connecting rectangular waveguide systems with circular waveguide antennas / feed components. It realizes high-efficiency mode conversion between standard rectangular waveguide (TE₁₀ mode) and circular waveguide (TE₁₁ dominant mode), making it an essential passive transition component in satellite communications, radar antenna feeds, radio astronomy, and high-power microwave systems.

Product Features

Perfect Mode Conversion

Achieves low-loss, low-reflection conversion between rectangular waveguide TE₁₀ and circular waveguide TE₁₁, effectively suppresses higher-order modes, ensuring signal purity and stable transmission.
Low VSWR & Low Insertion Loss

Adopts tapered or stepped matching structure with excellent full-band impedance matching.

Typical VSWR ≤ 1.10~1.20, insertion loss ≤ 0.1~0.3 dB.
High Power Capacity

All-metal integrated structure with silver-plated inner walls provides excellent heat dissipation. Power capacity is close to the rated value of the waveguide, suitable for high-power transmission and feed links.
Standard Flange Interfaces

One end with rectangular waveguide flange (UG/CPRG/FBP) and the other with circular waveguide flange.

Plug-and-play design with high versatility, allowing direct connection to antenna feeds, rotary joints, filters, etc.
