Abstract: Disclosed herein are integrated circuit (IC) packages, antenna boards, antenna modules, and communication devices (e.g., for millimeter wave communications). For example, in some embodiments, an antenna module may include: a logic die; a radio frequency front-end (RFFE) die in electrical communication with the logic die; and an antenna patch, wherein the RFFE die is closer to the antenna patch than the logic die is to the antenna patch.

Abstract: The disclosure is directed to a circuit arrangement and method that provide efficient concurrent transmit and receive, transmit only and receive only of wireless signals. In one implementation, a circuit arrangement is provided that incorporates uses a single antenna to achieve concurrent transmit and receive, transmit only and receive only of wireless signals. A dual amplifier structure may be provided, and at least one of the amplifiers associated with the dual amplifier structure is amplitude tunable in order to ensure that each amplifier of the dual amplifier structure provides substantially the same or the same signal amplification. Unwanted transmit signals detected by a receiving circuit arrangement may be used to cause a processor to generate a digital code word that is used to modify a signal amplification provided by at least one of the amplifiers associated with the dual amplifier structure.
