    Abstract: A multiple-input multiple-output (MIMO) antenna system for a mobile cellular network and method is described. The MIMO antenna system includes an array of dual-polarization patch antennas each having first and second polarization feed-points, a first polarization radio chain and a second polarization radio chain. The MIMO antenna system includes a beamformer coupled to the first and second polarization radio chains. The beamformer includes a beamformer channel for a respective feedpoint and further includes a transmit amplifier and a detector (coupler) coupled to a transmit amplifier output. In one mode of operation, a signal is transmitted via the first polarization feed-point of a dual-polarisation patch antennas and a replica of the transmitted signal may be sensed using the coupler at the output of the transmit amplifier and routed via the second polarization radio chain to a digital predistortion module. The digital pre-distortion module is configured to digitally pre-distort a signal for transmission dependent on the replica of the RF signal.

    Abstract: An integrated circuit comprising a package, phased antenna array and die. The die comprises a plurality of unit cells, wherein each unit cell is divided into quadrants. Each quadrant comprises a receiver terminal located on a first axis, and a transmitter terminal located on a second axis, wherein the first axis is orthogonal to the second axis, and there is mirror symmetry between the nearest neighbour quadrants in the unit cell. The package comprises a plurality of pairs of feed lines, each pair of feed lines comprising a receiver feed line and a transmitter feed line. The receiver feed line is connected to one of the receiver terminals and the transmitter feed line is connected to the transmitter terminal in the same die quadrant. The receiver feed line is orthogonal to the transmitter feed line. Each antenna element is coupled to a respective pair of feed lines.

    Abstract: An RF package assembly includes a stacked package-on-package arrangement of a first substrate and a second substrate. Each of the first and second substrates include RF signal pads and ground pads. An interface region between the stacked substrates couples the RF signal pads and ground pads of the first substrate to corresponding pads of the second substrate. The interface region includes galvanic connection regions providing a galvanic connection between the each of the first substrate ground pads and each of the corresponding second substrate ground pads. The interface region includes dielectric regions between each of the first substrate RF signal pads and the corresponding second substrate RF signal pads so that RF signals transmitted between the two substrates are capacitively coupled.
