AI Technical Summary
Existing Q/V band trackers suffer from several problems: insufficient width of the contact surface between the cover plate and the main body leads to contradictions in assembly connection and electromagnetic sealing; lack of effective phase adjustment means results in poor phase consistency of the sub-waveguide; and the thin-walled cavity is prone to deformation during processing, causing the cylindricity and coaxiality of the circular waveguide to exceed the standard.
The main body adopts an octagonal cross-section design, with a through-hole in the center and a coupling groove along the axial direction. The cover plate has an embedded strip, and the T-shaped coupling groove and the embedded strip are used to achieve sealing. The bottom surface of the embedded strip has an adjustment cavity for phase adjustment, and wax is poured in before processing to support and prevent the cavity from deforming.
Mass production of high-performance Q/V band trackers has been achieved, with a yield rate of over 95%, a production cycle shortened by 60%, and a significant reduction in overall cost, meeting the needs of high-throughput satellite communication ground stations.
