Product Details
Product Overview
Hardware developers engineering miniature satellite uplink terminals or small-scale mobile tracking stations often struggle with severe payload limits and intense thermal dissipation when using traditional mechanical dishes or heavy block amplifiers. The SDL-256B redefines professional transmit-only architectures by packing 256 active radiating elements into a flat panel weighing only 215g. Delivering a strong EIRP output greater than 34 dBW combined with arbitrary polarization tracking, it maintains cross-polarization isolation exceeding 25dB at center alignment. Operating flawlessly without physical wear across extreme temperatures from -40°C to +70°C, this sub-assembly offers a highly reliable LEO GEO satellite transmission component engineered to sustain critical data uplinks where space and power budgets are strictly capped.

FAQ
- How does the SmartFusion technology on the SDL-256B manage thermal performance in such a small form factor?
- Transmitting data generates concentrated heat, which can degrade performance in micro-sized arrays. The integrated SmartFusion engine operates as a real-time power optimization and beam management layer, precisely scaling the RF drive current fed to individual elements based on active link paths. This keeps total power consumption locked under an efficient 60W, preventing localized thermal spikes and protecting hardware integrity during continuous operation.
- What are the physical deployment advantages of the integrated radome design on this panel?
- The integrated radome design molds the protective outer face directly onto the multi-layer phased array substrate, completely removing bulky outer housings or physical integration gaps. This allows the SDL-256B to achieve an ultra-thin 14.5mm profile and an exceptional weight profile of ≤215g. This makes it ideal for embedding directly into miniature drone payloads, portable tactical briefcase networks, or low-profile vehicular roof structures.
- What type of connection interfaces and electrical inputs does this Ku-band transmitter require?
- This ku-band satellite transmitter sub-assembly uses a secure, aviation-grade J30J-21 multi-pin control port to handle both electronic beam steering commands and main power lines. The hardware runs on a low-voltage DC 12V supply (with a safe operational tolerance range of 11V to 13V), routing the raw intermediate frequency (IF) uplink signals cleanly in through a standard SMA-K RF interface.
