Abstract
A method and apparatus pertains to a mixer. A first differential pair has a first and a second drain lead coupled to a first and a second gate lead respectively. A first transformer is coupled to the first and the second drain lead. A second differential pair has a third and a fourth gate lead coupled to the second and the first gate lead of the first differential pair respectively. A third differential pair has a fifth and a sixth gate lead coupled to the first and the second gate lead of the first differential pair if the mixer is performing as a down converter, and has fifth and sixth drain leads coupled to third and fourth drain leads of the second differential pair respectively. A second transformer is coupled to a first and a second base lead of the second and the third differential pair respectively.
