    Abstract: A transceiver in a wireless communication system is provided. The transceiver includes a first circuit configured to convert a digital signal having a third bandwidth, a second circuit configured to separate the analog signal into a first analog signal corresponding to the first band and a second analog signal corresponding to the second band, up-convert the first analog signal and the second analog signal to generate a first radio frequency (RF) signal in the first band and a second RF signal in the second band, and output an RF signal having the third bandwidth, and a third circuit configured to separate the RF signal into the first RF signal and the second RF signal, adjust a phase of the first RF signal for beamforming in the first band, and adjust a phase of the second RF signal for beamforming in the second band.

    Abstract: A fan-out semiconductor package includes a frame having a recess portion, and a semiconductor chip having an active surface on which a connection pad is disposed and an inactive surface opposing the active surface, the semiconductor chip being disposed in the recess portion. One or more through-grooves are disposed around the recess portion and each penetrate through at least a portion of the frame to each extend in a respective direction along a respective side surface of the semiconductor chip. A metal layer is disposed on side walls of the one or more through-grooves, and an encapsulant covers at least a portion of each of the frame and the semiconductor chip and fills at least a portion of the recess portion. A connection structure is disposed on the frame and the active surface of the semiconductor chip, and includes a redistribution layer electrically connected to the connection pad.
