Rectangular to Circular Waveguide Transition

Huasen Microwave's Rectangular to Circular Waveguide Transition (RCA) is designed for efficient microwave signal conversion, solving the connection problems between waveguide systems with different cross-sections.
Key advantages:
- Efficient mode conversion: Converts the TE10 mode in the rectangular waveguide evenly to the TE11 mode in the circular waveguide.
- The full series has a standing wave ratio (VSWR) of ≤ 1.1.
- Precision size design: The diameter of the circular waveguide strictly matches the international standard BY series.
- Typical lengths: 200-920mm (low-frequency) and 50-160mm (high-frequency).
