This disclosure relates to a transceiver element comprising receiving circuitry, down-converting circuitry, extracting circuitry and output circuitry. The receiving circuitry is configured to receive a radio frequency signal via an antenna element associated with the receiving circuitry. The radio frequency signal comprises a first received signal part and a second received signal part. The down-converting circuitry is configured to down-convert the radio frequency signal to provide a down-converted signal. The down-converted signal comprises a first down-converted signal part corresponding to the first received signal part and a second down-converted signal part corresponding to the second received signal part. The extracting circuitry is configured to extract at least the second down-converted signal part from the down-converted signal. The output circuitry is configured to provide an output signal comprising a first output signal part and a second output signal part. The first output signal part comprises at least a first intermediate signal part which comprises at least the first down-converted signal part. The second output signal part comprises at least the second down-converted signal part extracted from the down-converted signal. Corresponding transceiver, wireless communication apparatus, method and computer program product are also disclosed.

Transceiver element for beamforming

A MIMO transceiver has a plurality of analog processing subsystems that each includes at least one antenna, a duplexer, at least one power amplifier, at least one mixer, an interface connectable to a baseband processing subsystem, and the MIMO transceiver has one or more analog radio frequency processing chips. Each analog processing subsystem of the plurality of analog processing subsystems is on a single one of the analog radio frequency processing chips, and each analog radio frequency processing chip comprises a metallization on at least one side of the chip and wherein the metallization comprises integration of the at least one antenna.

Analog processing system for massive-MIMO

An analog processing subsystem is disclosed. Said subsystem comprising at least one antenna (), a duplexer (), at least one power amplifier (), at least one mixer () and an interface connectable to a baseband processing subsystem. The at least one mixer () is adapted to down-convert and inphase/quadrature&#x2014;IQ&#x2014;demodulate a received analog radio frequency signal, received by the at least one antenna (), to provide a received analog baseband signal and to IQ-modulate and up-convert a transmit analog baseband signal, to be transmitted by the at least one antenna (), to provide a transmit analog radio frequency signal. The analog processing subsystem is comprised on a single analog radio frequency processing chip () comprising a metallization on at least one side of the chip for integration of the at least one antenna ().
