Abstract
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.
Claims14
A multiple input multiple output (MIMO) transceiver arrangement comprising a plurality of removable analog processing subsystems operatively connected to at least one baseband processing subsystem, and one or more analog radio frequency processing chips,
- wherein the plurality of analog processing subsystems comprises a first number of analog processing subsystems, wherein the at least one baseband processing subsystem comprises a second number of baseband processing subsystems, and wherein the first number exceeds the second number,
- each analog processing 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,
- wherein the at least one mixer is adapted to down-convert and inphase/quadrature (IQ) 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,
- wherein the mixer comprises at least one input terminal connected to an input terminal of the interface for acquiring the transmit analog baseband signal and at least one output terminal connected to an output terminal of the interface for providing the received analog baseband signal,
- wherein the at least one antenna is directly connected to the duplexer, the duplexer is directly connected to the at least one power amplifier, the at least one power amplifier is directly connected to the at least one mixer and the at least one mixer is directly connected to the interface,
- wherein each analog processing subsystem of the plurality of analog processing subsystems is comprised on a single one of the analog radio frequency processing chips, and
- wherein 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.
