Abstract:
A receiver circuit comprising a connection portion for guiding each one of a first predefined number of carrier signals of multiple carriers to one of a number of receive branches, each receive branch comprising at least one amplifier load structure, the number of receive branches being equal to the first predefined number. The receiver circuit also comprises a mixing portion for generating a second predefined number of mixed carrier signals on each receive branch by mixing a carrier signal on each one of the receive branches with a number of local oscillator frequencies equal to the second predefined number, and a selection portion for selecting one of the second predefined number of mixed carrier signals on each receive branch to be output via a number of output paths equal to the first predetermined number to a digital data path.
