ADI delivers electronic beam forming technology for LEO satellite constellation Analog Devices (ADI) is collaborating with MDA to deliver the beam forming integrated circuit (BFIC) to be used in MDAâs phased array antenna for the Telesat Lightspeed low earth orbit (LEO) satellite constellation. Telesat Lightspeed, comprising of 298 next-generation satellites, is due to to launch in the second half of 2023 and is intended to redefine global broadband connectivity for commercial, government and defence markets. LEO satellites, rather than operating from a fixed position, move across the sky and must dynamically steer communication beams to maintain uninterrupted and high-speed connectivity to ground terminals. The BFIC solution from ADI is highly reliable while performing under extreme temperatures and cosmic radiation for the full 10- to 12-year lifespan of each satellite.
