Overview

Description

Global demand for high-speed internet and reliable communication services is growing due to the increasing number of connected devices and the need for continuous connectivity. In response to this demand, Renesas offers a full duplex satellite communications system featuring flat-panel electronically steered array antennas (ESAs). These antennas utilize Renesas beamforming ICs for fast electronic beam positioning and satellite tracking.

System Benefits​:

  • Lower weight and profile enhance portability and ease of installation.
  • Fast beam steering ensures seamless handover between satellites.
  • Dual independent Rx beams support simultaneous multi-satellite and multi-orbit operation, enhancing connectivity and reliability.
  • Adaptable for half-duplex applications: Tx and Rx antennas can be merged into a single board, reducing the bill of materials (BOM).
