Description

The F5280 is a 4-channel TRX half-duplex silicon IC designed

using a SiGe BiCMOS process for 28GHz 5G phased-array

applications. The core IC has very flexible gain and phase control

on each channel to achieve fine beam steering and gain

compensation between radiating channels. The core design

includes standard SPI protocol that operates up to 50MHz with fast-

beam switching, fast beam-state loading, and fast four on-chip

beam storage.
