Abstract
Heterodyne commutating apparatuses and methods for creating the heterodyne commutating apparatuses are disclosed. The heterodyne commutating mixer includes a plurality of switches for transferring a radio frequency input signal sequentially during a plurality of local oscillator period timeslots to a plurality of output capacitors. The heterodyne commutating mixer also includes a plurality of inductors added across differential in-phase output terminals and quadrature output terminals. Values of inductance and capacitance are set to achieve resonance at an output intermediate frequency.
