The SUMMIT 2629™, an eight-channel RF front-end for 28 GHz, 5G phased array antenna systems fabricated in RF-SOI. The SUMMIT 2629 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 26.5 to 29.5 GHz, the SUMMIT 2629 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 2629 provides two sets of four channels for two antenna polarizations – a total of eight channels per RFIC.
