Active and passive dual local oscillator mixers comprising triple gate mixer circuits or exclusive NOR switch (XNOR-SW) circuits.

摘要

A dual local oscillator (LO) mixer is disclosed. The dual-LO mixer receives an input signal, a first reference signal of a first reference frequency, and a second reference signal of a second reference frequency, and performs a frequency translation to convert the input signal into an output signal, wherein the frequency difference between the input signal and the output signal is a sum or a difference of the first reference frequency and the second reference frequency. Also disclosed is the use of such a mixer a radio transmission system including both a transmitter and receiver which comprise dual-LO mixers.
