SUMMIT3741™
39 GHz Beamforming Front End IC
Operating from 37 GHz to 41 GHz
The Summit3741™ integrates novel power amplifiers, low noise amplifiers, T/R switching, beamformers, calibration, gain control, beam table memory, temperature and power telemetry, and high-speed SPI control for a front-end module with optimal partitioning for 5G infrastructure.
The device is suitable for Antenna-in-Package (AiP) implementations, as well as conventional chip-on-board integration through the use of interposers.
SUMMIT3741 also features enhanced and cutting-edge digital integration, uniquely enabled by the GLOBALFOUNDRIES® (GF®) 45RFSOI process, which has inherent advantages over other semiconductor technologies for mmWave applications.
