Overview
Modular Phased-Array SATCOM for Marine & Mobile Platforms
Compact flat-panel SATCOM built around phased-array antennas. The system is split into two primary signal chains — Receive and Transmit — enabling fully electronic beam steering, C/Ku-band support, and modular integration for land, sea, air or space platforms.
Signal Chains — Quick View
Detailed flow
- Phased-array antenna receives satellite RF with directional gain.
- Beamforming ICs apply precise phase & amplitude corrections for directional reception.
- RF splitter routes signals to parallel paths for redundancy/processing.
- LNA amplifies weak signals with minimal added noise.
- Downconverter converts RF → IF/baseband for processing.
- Baseband processor / modem demodulates and hands data to service layers.
Design goal: maximize SNR, preserve signal integrity, enable flexible routing to downstream processors.
Detailed flow
- Baseband processor prepares uplink symbols or relays data streams.
- Upconverter converts IF/baseband → RF.
- Power amplifier (PA) raises RF to required EIRP for uplink.
- Beamforming IC & RF splitter distribute RF to transmit elements and apply steering vectors.
- Phased-array elements radiate the steered uplink to satellite.
Design goal: accurate EIRP control and beam steering with minimal distortion and spectral cleanliness.
Architecture Notes
- Supports C-band and Ku-band operation.
- Flat-panel, compact antenna form factor—no mechanical gimbals required.
- Modular & scalable: add parallel RF chains or higher-power PAs as needed.
