A mixer may include a linearization circuit. The linearization circuit may include and operation amplifier, a first pass device, a second pass device, a first feedback resistor, and a second feedback resistor. Each of the first pass device and the second pass device may have a gate terminal, a first non-gate terminal, and a second non-gate terminal and coupled to its gate terminal to an output terminal of the operational amplifier and configured to be coupled at its first non-gate terminal to a high potential source. Each of the first feedback resistor and the second feedback resistor may have a first terminal and a second terminal, the first terminal coupled to the positive input terminal of the operational amplifier and the second terminal coupled to the second non-gate terminal of an associated pass device and the positive polarity of the differential baseband output.
