Direct conversion receiver circuit for concurrent reception of multiple carriers

A receiver circuit at a terminal in a communication system, the receiver circuit comprising:

• an input portion configured to input a plurality of carrier signals of multiple carriers via a plurality of amplifier input stages;
• a connection portion configured to guide each one of a first predefined number of carrier signals in the plurality of carrier signals to one of a number of receive branches, each of the receive branches comprising at least one amplifier load structure, the number of the receive branches being equal to the first predefined number;
• a mixing portion configured to generate a second predefined number of mixed carrier signals on each of the receive branches by mixing one of the carrier signals on each one of said receive branches with a number of local oscillator frequencies equal to the second predefined number, wherein at least two of the local oscillator frequencies are different from each other;
• a selection portion configured to select one of the second predefined number of the mixed carrier signals on each of the receive branches;
• and
• an output portion configured to output a number of the selected mixed carrier signals on the receive branches via a number of output paths to a digital data path, the number of the selected mixed carried signals being equal to the first predetermined number, and the number of the output paths being equal to the first predetermined number.
