Overview
The 474750A (AEQE) is a component of a base station for mobile networks. It features 64 transmit/receive (T/R) paths with support for 64T64R MIMO, 256QAM modulation, and 200 MHz instantaneous bandwidth. The unit supports digital beamforming, a 32TRX + 32TRX split mode, and connects to the baseband unit via eCPRI over SFP28 ports.
