Product Details
Product Overview
Hardware integrators building low-profile satellite uplink terminals frequently face thermal bottlenecks and severe weight constraints when deploying traditional high-power amplifiers and motorized dishes. The SDL-768A resolves these field challenges by condensing an entire 768-element transmit system into a solid-state substrate measuring just 12.5mm thick. Delivering a high-efficiency EIRP output greater than 44 dBW combined with arbitrary polarization tracking, it maintains cross-polarization isolation exceeding 25dB at center alignment. Operating seamlessly without structural degradation from -40°C to +70°C, this sub-assembly offers a highly reliable LEO GEO satellite transmission component designed to sustain critical broadband uplinks where physical space and payload capacities are extremely restricted.

FAQ
- Why does the SDL-768A omit internal up/down converters from its design architecture?
- By keeping the up-conversion modules external to the main array board, the SDL-768A achieves a highly streamlined 12.5mm profile and keeps its total weight at ≤640g. This layout prevents localized thermal stacking on the active radiating face during high-power transmit cycles, granting developers full system flexibility to route the intermediate frequency (IF) transmission lines via a standard SMA-K RF interface.
- How does the SmartFusion technology optimize the power efficiency of this transmit array?
- Transmitting data to a satellite requires considerable power, which normally generates excessive heat in small-form phased arrays. The integrated SmartFusion engine acts as a dynamic beam management and power distribution layer, precisely scaling the RF drive current to individual antenna elements based on the exact transmission link requirements. This optimization caps the total system power draw at ≤165W while keeping output efficiency remarkably high.
- What type of connection interface and power input does this Ku-band transmitter require?
- This ku-band satellite transmitter module uses a rugged, aviation-grade J30J-21 multi-pin control interface to handle both the digital beam steering commands and the main power lines. The hardware runs on a low-voltage DC 12V supply (with a functional operating tolerance range of 11V to 13V), ensuring simple integration into mobile terrestrial terminals, unmanned aircraft, or portable tactical briefcase networks.
