＃세미나 요약:

First, power-efficient RF receiver designs are presented specifically for advanced-LTE cellular applications. The proposed two single-ended receiver architectures can fully support multiple-channel RF signals for advanced carrier aggregation scenarios with maximum design flexibility depending on the RF front-end module configuration and target applications. Second, the first demonstration of 5G millimeter-wave hybrid front-ends for phased-array transceiver in order to show efficient transmitter performance with low cost and compact area are presented. The configuration of the proposed hybrid front-ends is CMOS-based front-ends combined with compact GaAs HEMT-based power-cell array to obtain all the benefits of silicon and III-V technology. The architecture and design method of a millimeter-wave TX/RX combiner for antenna-port sharing suitable for the proposed hybrid structure are newly introduced.
