Patent ID: 8862086

Claim:
A mixer configured to sample a received input signal at a predefined oscillator frequency to generate a sampled input signal, and switch a polarity of the sampled input signal at a predefined polarity switching frequency to generate a polarity switched sampled input signal, wherein the polarity of the polarity switched sampled input signal is maintained as compared to the received input signal in a first polarity state and is reversed as compared to the received input signal in a second polarity state, wherein the first polarity state and the second polarity state switch between each other according to the predefined polarity switching frequency, wherein the oscillator frequency is selected to be a multiple or an integer multiple of the polarity switching frequency; and wherein the mixer is configured to switch the polarity of the sampled input signal at points in time when the input signal is received at an input of the mixer and an output of the mixer at which the sampled input signal is provided is decoupled from each other.
