Abstract
Disclosed is a frequency mixer. The frequency mixer includes a first matching circuit that generates a matched local oscillator (LO) signal based on an LO signal, a non-linear circuit that generates a non-linear LO signal based on the matched LO signal, a second matching circuit that generates a matched radio frequency (RF) signal based on an RF signal, a mixing circuit that generates a mixed signal based on a mixing of the non-linear LO signal and the matched RF signal, a third matching circuit that generates an intermediate frequency (IF) signal based on the mixed signal, wherein the non-linear circuit includes a non-linear transistor, a bias transistor, and an internal matching circuit connected in series.
