An inflatable straight waveguide is a specialized RF transmission line designed for applications where weight reduction, flexibility, and environmental sealing are critical—such as in aerospace, field-deployable radar, or temporary test setups. 🛠️ Key Technical Features: - Structure: A rectangular waveguide with an integrated inflatable bladder or pressurizable cavity, typically installed along the narrow wall. This allows the waveguide to maintain structural integrity and RF performance while being lightweight and collapsible. - Frequency Range: Models span from 0.32 GHz to 40 GHz, depending on waveguide size (e.g., WR2300 to WR28). - VSWR: Typically ≤ 1.05–1.10, ensuring minimal reflection across the passband. - Materials: - Body: Aluminum or copper for conductivity and weight savings. - Inflatable Section: Flexible dielectric or metallic-coated fabric, engineered to maintain shape and RF continuity under pressure. - Air Pressure Rating: Up to 0.1–0.2 MPa, depending on model. - Length Options: Common lengths include 50 mm to 200 mm, with custom options available.
