Product Details
Product Overview
System architects designing large-scale satellite ground stations or high-gain mobile terminals often face massive development hurdles when trying to scale flat-panel systems without adding extreme bulk and power overhead. The SDL-256C eliminates these scalability bottlenecks by introducing a fully tileable, brick-style building block that allows multiple panels to splice together seamlessly into a larger aperture. Delivering a baseline G/T ratio equal to or greater than 4.5 dB/K and supporting dual-circular polarization combining into arbitrary linear tracking, it captures deep data streams without signal degradation. By combining dual-beam processing into an ultra-thin 15mm modular frame that operates reliably from -40°C to +70°C, it offers a highly scalable LEO GEO satellite reception platform engineered to adapt to custom aperture requirements.

FAQ
- How does the tileable architecture of the SDL-256C benefit custom terminal designs?
- The SDL-256C is designed as a fully modular block, meaning multiple 190mm x 190mm panels can be physically and electronically tiled together to create custom, large-aperture array faces. This allows engineers to scale up the system gain (G/T ratio) and directional performance easily to match specific bandwidth demands, without needing to develop entirely new custom antenna hardware from scratch.
- What are the operational advantages of the dual-beam capability built into this panel?
- Unlike standard single-beam panels, the SDL-256C features an advanced true dual-beam processing architecture. This allows the array tile to track and lock onto two separate satellites simultaneously within its wide scan range (0–65° elevation). This feature is critical for fast-moving Low-Earth Orbit (LEO) constellations, enabling seamless, make-before-break handovers between descending and ascending satellites without dropping data packets.
- What type of electrical interfaces are used, and does it include on-board beam control?
- This ku-band satellite receiver tile utilizes a standard SPI control interface for command routing and high-frequency SMP connectors for its RF combining path. To maximize system-level integration flexibility and maintain an ultra-low 40W power profile per tile, the board does not contain independent beam-control (wave control) hardware, allowing a centralized external controller to manage the phase and steering parameters of a fully tiled array matrix smoothly.
