Description

The F5268 is an eight-channel TRX half-duplex silicon IC designed

using a SiGe BiCMOS process for 26GHz dual polarization 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 and fast beam-state loading.
