Abstract
An example of a receiver circuit is disclosed. The receiver circuit comprises an input for receiving a radio frequency signal, an output for providing an output signal of the receiver circuit, a receive path, wherein the receive path is connected between the input and the output of the receiver circuit, and a feedback path, wherein an input of the feedback path is connected to the output of the receiver circuit. The receiver circuit also comprises a transformer, wherein an output signal of the feedback path is combined with the received radio frequency signal in the receive path to form a first signal. The receive path comprises a first mixer for downconverting the first signal by a local oscillator frequency, and an amplifier for amplifying the downconverted first signal. The feedback path comprises a second mixer for upconverting a signal in the feedback path by said local oscillator frequency. The combination of the output signal of the feedback path with the received radio frequency signal is achieved by means of the transformer.
