The F5288 is an eight-channel TRX half-duplex silicon IC designed using a SiGe BiCMOS process for 28GHz 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.
