Product Details
Product Overview
Terminal manufacturers engineering next-generation Ka-band satellite receivers frequently encounter intense thermal bottlenecks and severe weight penalties when attempting to capture high-throughput downlinks using traditional parabolic dishes or bulky flat panels. The SDL-Rx1024 solves these hardware challenges by packing a massive 1,024-element matrix into a solid-state flat panel that is only 15mm thick. Achieving a high-efficiency G/T ratio equal to or greater than 6.5 dB/K combined with arbitrary polarization tracking, it maintains cross-polarization isolation equal to or greater than 30dB at center alignment. Operating flawlessly without mechanical wear across extreme outdoor temperatures from -40°C to +70°C, this panel provides a highly dependable LEO GEO satellite reception component built to sustain deep data pipes where minimal physical profile and high gain are paramount.

FQA
- Why does the SDL-Rx1024 omit internal up/down conversion circuitry from its design?
- By keeping the down-conversion stages external to the primary antenna board, the SDL-Rx1024 achieves an ultra-thin 15mm profile and keeps its total weight at ≤675g. This architectural layout prevents localized thermal stacking on the active radiating panel across the demanding 17.7GHz–21.2GHz Ka-band spectrum, giving system integrators the flexibility to route raw RF lines through standard SMA-K interfaces to their own backend receivers.
- How does SmartFusion technology optimize power efficiency across a large 1,024-element array?
- Driving 1,024 active elements simultaneously usually demands significant power and generates intense heat. The embedded SmartFusion engine functions as an intelligent signaling and power management layer, dynamically scaling the active current draw fed to individual elements based on real-time satellite link characteristics. This optimization caps total power consumption at an ultra-efficient ≤56.5W without compromising tracking sensitivity.
- What type of connection interface and electrical input does this Ka-band receiver require?
- This ka-band satellite receiver component uses a secure, aviation-grade J30J-21 multi-pin control port to handle both high-speed electronic beam steering tracking commands and electrical inputs. The hardware runs efficiently on a low-voltage DC 12V supply line (with a functional operating tolerance range of 11V to 13V), ensuring seamless deployment in mobile vehicle mounts, portable field kits, or compact airborne sub-assemblies.
