Digital Beamforming is a signal processing technique used in satellite communications to electronically steer and shape antenna beams. It involves processing digitized signals from an array of antenna elements, manipulating their phase and amplitude to optimize radiation patterns. This method enhances flexibility, precision, and efficiency in directing satellite communication signals.
SatixFy’s innovative Digital Beamforming (DBF) technology is the basis of the company’s Electronically Steered Multi-Beam Antenna Array (ESMA) product-line.
The technology highlights of SatixFy digital beamforming are:
- True time delay (TTD) beamforming that supports a very large bandwidth free of squint effects.
- Multi-layer architecture with up to 8 GHz per layer.
- Scalable multi-beam architecture: from 8 1GHz beams to 128 60 MHz beams.
- Low power logic design
- RF sampling allows a reduction of the number of components and power consumption. Supports direct sampling up to the Ka band.
- Pre-distortion per antenna element power amplifier.
