Abstract:
An active filter circuit includes an inductance-capacitance (LC) circuit (110) for wireless frequency input, a bi-directional mixer (120) and a filter impedance (130) series-coupled across at least part of the LC circuit (110), and another mixer (420) coupled to at least some portion of the LC circuit. Other circuits, processes, receivers, transmitters and transceivers are disclosed.
