24 GHz Beamforming Front End IC
Operating from 24.25 GHz to 27.5 GHz

The SUMMIT2427e™ is an eight-channel RF front-end for 24 GHz, 5G phased array antenna systems fabricated in RF-Silicon on Insulator (RF-SOI)

” Sivers Semiconductors is indeed offering a real performance breakthrough which will translate to higher performance and lower cost mmWave phased array systems.”
Daniel Kang
Head of Digital Solution Team, Dreamtech

The SUMMIT 2427e was designed to address the challenges constraining 5G mmWave performance by:

  • Extending the link range to decrease infrastructure costs and improve customer satisfaction.
  • Reducing power consumption and thermal dissipation.
  • Reducing antenna array complexity and overall RF front-end cost.

Operating from 24.25 to 27.5 GHz, the SUMMIT 2427e RFIC integrates power amplifiers (PA), low noise amplifiers, T/R switching, beamformers with beam table memory, calibration, gain control and temperature and power telemetry with a high-speed system peripheral interface (SPI) for control. A single SUMMIT 2427e provides two sets of four channels for two antenna polarizations – a total of eight channels per RFIC.
