Abstract: A beamformer device for a multiple-input, multiple-output (MIMO) antenna system and method of operating a beamformer device is described. the beamformer device includes a number of beamformer channels. Each beamformer channel includes a RF terminal, an antenna connection terminal; and a power detector having a power detector output, The beamformer device includes a digital control interface comprising a serial data input and a serial data output; a control input coupled to the serial data input; and a beamformer monitor output configured to be selectively coupled to either the serial data output or the power detector output of one of the beamformer channels.

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: A phased-array antenna system includes a substrate and a plurality of sub-arrays. Each sub-array comprises an array of patch antennas arranged on a first major surface of the substrate; a plurality of beamformer devices coupled to the array of patch antennas; a multi-channel up-down converter (UDC) and a combiner-splitter coupled to the multi-channel UDC. The combiner-splitter is configured to split a signal provided by the UDC and provide the signal to each of the plurality of beamformers and/or to combine signal provided by the plurality of beamformers and to provide the combined signal to the UDC. Each sub-array also includes an integrated device comprising the multi-channel UDC and the combiner-splitter. The integrated device and the plurality of beamformer devices is arranged on a second major surface of the substrate opposite the first major surface. The integrated device is arranged between at least two beamformer devices.

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 signal is transmitted via the first polarization feed-point of a dual-polarisation patch antennas and a replica of the transmitted signal is sensed (detected) using the second polarization feed-point of the same patch antenna. This replica signal is used by a digital predistortion module to apply predistortion to a subsequently transmitted signal.
