Product Details
Product Overview
System integrators building miniature satellite uplink terminals or man-portable tracking kits face severe payload liabilities when utilizing traditional motorized dishes or bulky amplifiers. The SDL-384A eliminates these design barriers by packing 344 active transmit elements into a rugged flat panel weighing less than a standard smartphone. Generating an EIRP greater than 37 dBW paired with an arbitrary polarization tracking structure, it maintains a cross-polarization isolation equal to or greater than 25dB at center alignment. Operating seamlessly without mechanical wear across an expansive temperature range from -40°C to +70°C, this sub-assembly provides a highly dependable LEO GEO satellite transmission component for tactical or commercial applications requiring absolute mobility and high uplink reliability.

FAQ
- What are the integration benefits of the external up/down converter design on the SDL-384A?
- By leaving up-conversion circuitry to external hardware, the SDL-384A minimizes localized heat generation on the active radiating panel and achieves a thin 14.5mm profile weighing ≤300g. This gives engineering teams full architectural freedom to match the transmit array with their preferred external intermediate frequency (IF) gear via the integrated SMA-K RF interface.
- How does SmartFusion technology control power draw and thermal generation during high-power transmission?
- The built-in SmartFusion architecture serves as an intelligent power-scaling engine. Instead of supplying static power across the panel, it dynamically optimizes the RF drive currents fed to the 344 individual elements based on real-time link requirements. This keeps total power consumption capped at an ultra-efficient 75W, preventing thermal spikes in enclosed spaces.
- What type of electrical connections and power infrastructure does this Ku-band transmitter require?
- This ku-band satellite transmitter sub-assembly uses a secure, industry-standard J30J-21 multi-pin control port to manage both beam steering data commands and electrical inputs. It runs on a low-voltage DC 12V input (with a safe operational tolerance range of 11V to 13V), making it highly compatible with drone battery cells, portable field packs, or small vehicle electronics lines.
