About
The waveguides are engineered to provide reliable signal transmission within specified frequency bands for flight communication equipment and antenna feed systems. They were first released in 2008 and boast a guaranteed service life of 15 years. The estimated production and delivery time is one month. These components have a flight heritage, having been qualified on the Loutch-5 spacecraft. They support a wide range of frequency bands including C, X, Ka, Ku, and Q, with a Standing Wave Ratio (SWR) between 1.1 and 1.2. The internal channel can be coated with silver, gold, or oxide, with varying maximum lengths depending on the coating type: up to 500 mm for silver, up to 250 mm for gold, and up to 1500 mm for oxide. The pipe wall thickness ranges from 0.65 to 1.6 mm, and they can accommodate up to 4 bends. The internal channel roughness is specified as Ra2.5. These waveguides are integral elements of antenna feed systems and flight communication equipment paths across different frequency bands.
