ABSTRACT:
A frequency mixer includes a semiconductor substrate. An input current feedback amplifier is formed on the semiconductor substrate and receives a radio frequency (RF) signal and a local oscillator (LO) signal. An inverting current feedback amplifier is formed on the semiconductor substrate and connected to the input current feedback amplifier for inverting the LO signal and producing a half-wave signal. An output current feedback amplifier is formed on the semiconductor substrate and connected to an output of the input and inverting current feedback amplifiers and operative as an inverting summer for the RF and LO signals such that the output polarity of the RF signal is reversed.
