The invention relates to a novel receiver circuit. The receiver circuit has a local oscillator (10), a quadrature modulator (20), a first mixer (31), and a second mixer (32). According to the invention, a first input of the quadrature modulator (20) is connected to a second signal input of the receiver circuit, and a second input of the quadrature modulator (20) is connected to the local oscillator (10). In addition, a first input of the first mixer (31) is connected to a first signal input of the receiver circuit, a second input of the first mixer (31) is connected to an output of the quadrature modulator (20), and an output of the first mixer (31) is connected to a first signal output of the receiver circuit. A first input of the second mixer (32) is connected to the second signal input, a second input of the second mixer (32) is connected to the output of the quadrature modulator (20), and an output of the second mixer (32) is connected to a second signal output of the receiver circuit. |
