Abstract: A family of radio frequency (RF) filter circuits that use radio frequency linear mixers to controllably separate desired frequency spectrum from undesired frequency spectrum, and convert signals from one frequency to another, permitting inclusion in a closed- or open-loop control circuit that supports rapid dynamic manipulation of the filter circuit's center frequency and bandwidth.

Abstract: A linear frequency converter or mixer design that utilizes linear time-varying devices and that avoids interaction between the local oscillator (LO) current and other signals inside the mixer, thus achieving high linearity and signal purity. This mixer also uses a LO frequency at least two times lower than conventional mixers, hence improving isolation between different system partitions. This class of mixer may not require a power supply.
