A mixer for mixing a radio frequency signal is described. The mixer includes a local oscillator input, a phase adjustment module, and at least one mixing channel. The local oscillator input is configured to receive a local oscillator signal. The phase adjustment module is configured to control a phase of the local oscillator signal in order to add a desired amount of delay to the local oscillator signal, thereby generating at least one adapted oscillator signal. The at least one adapted oscillator signal has a desired phase difference compared to the local oscillator signal. The at least one mixing channel includes at least one mixer unit having at least one signal input. The at least one mixing channel is configured to receive the at least one adapted oscillator signal. The at least one mixing channel further is configured to forward the adapted oscillator signal to the mixer unit. The at least one signal input is configured to receive an input signal. The at least one signal input further is configured to forward the input signal to the mixer unit. The mixer unit is configured to mix the at least one adapted oscillator signal with the input signal, thereby generating a mixer output signal.
