The F5280 is a 4-channel TRX half-duplex silicon IC designed using a SiGe BiCMOS process for 5G phased-array 应用s at n257/n261 bands. The core IC has flexible gain and phase control on each channel to achieve fine beam 方向盘 and gain compensation between radiating channels. The core design includes standard SPI protocol that operates up to 50MHz with fast beam-方向盘 modes.
