SUMMIT2427 Image

The SUMMIT2427e™ from Sivers Semiconductors is a Beamforming Front-End IC that operates from 24.25 to 27.5 GHz. It 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. This 8-channel IC has two sets of four channels for two antenna polarizations and enables two data streams supporting 2 MIMO layers. It is fabricated using RF-Silicon on Insulator (RF-SOI) technology and is designed to address the challenges constraining 5G mmWave performance. The IC has ultra-low transmit and receive mode power consumption.

The SUMMIT2427e™ provides Tx/Rx independent beam directions with a variable gain of 16 dB (in 0.5 dB steps) and a 6-bit 360° phase shifter in each path. This IC includes extensive on-chip temperature and power sensing and on-chip gain control for temperature compensation. It is available in a WLCSP package and is ideal for 5G phased array systems, fixed wireless access (FWA), and satellite applications.
