Abstract
Embodiments of power efficient radio frequency mixers are provided. A generalized impedance matched low-voltage active mixer circuit technique, which utilizes a plurality of commutator cells and transformers, is disclosed. The active mixer techniques are reconfigurable between various operation configurations based, at least in part, on selectively activating at least one of a plurality of commutator cells. The low voltage active mixer function is coupled to an impedance matched amplifier which can be bypassed allowing changes in the gain of the mixer circuit suites while preserving impedance matching.
