Abstract:
An analog beamforming transmitter includes: a plurality of beamforming transmission circuits coupled in parallel between a signal input and an array of antenna ports, wherein the signal input is configured to receive an analog complex-valued communication signal having an in-phase and a quadrature component, wherein each antenna port of the array of antenna ports is configured to provide a dual-polarized antenna signal having a first polarization component and a second polarization component, wherein each beamforming transmission circuit is coupled between the signal input and a respective antenna port of the array of antenna ports, wherein each beamforming transmission circuit comprises a first coefficient input for receiving a first analog complex-valued beamforming coefficient a set of first analog complex-valued beamforming coefficients and a second coefficient input for receiving a second analog complex-valued beamforming coefficient of a set of second analog complex-valued beamforming coefficients.
