Abstract: A mixer circuit includes a single-ended to differential converter, first and second transistors, first to fourth inductive transmission lines, and a mixer. The first and second transistors receive a differential input voltage signal pair from the single-ended to differential converter and generate a differential input current signal pair. The mixer mixes the differential input current signal pair with a differential oscillatory voltage signal pair. The first and second inductive transmission lines are configured such that an equivalent input impedance seen into the first and second transistors matches an equivalent output impedance seen into the first single-ended to differential converter.
