摘要： Radio frequency (RF) filters configured to filter undesired signal components (e.g., noise and harmonics) from RF signals are disclosed. In one embodiment, an RF filter includes a first inductor coil having a first winding and a second inductor coil having a second winding and a third winding.

The second winding is connected to the third winding such that the first mutual magnetic coupling and the second mutual magnetic coupling are in opposition. In this manner, the first inductor coil and the second inductor coil may be provided in a compact arrangement while providing weak mutual magnetic coupling between the first inductor coil and the second inductor coil.

摘要： The present disclosure relates to a circuit for suppressing unwanted magnetic interference. The circuit can have a transformer having a first coil, a first pair of input terminals, and a first pair of output terminals. The transformer can produce a first magnetic field. The circuit can also have a harmonic trap. The harmonic trap can have a second coil and a second pair of input terminals operably coupled to the first pair of input terminals. The harmonic trap can produce a second magnetic field opposing the first magnetic field. The harmonic trap can suppress electrical signals of at least one of the first input terminals and the first output terminals of the transformer at a resonant frequency of the harmonic trap. The harmonic trap can also suppress the first magnetic field in a far field.

摘要： Circuitry, which includes a package interface, a radio frequency (RF) amplification circuit, and a closed-loop gain linearization circuit. The package interface receives an RF signal and provides an amplified RF signal. The RF amplification circuit amplifies the RF signal in accordance with a gain of the RF amplification circuit so as to generate the amplified RF signal. In one embodiment, the closed-loop gain linearization circuit is configured to endogenously establish a target gain magnitude using the RF signal and linearize the gain of the RF amplification circuit in accordance with the target gain magnitude. By endogenously establishing the target gain magnitude using the RF signal, the closed-loop gain linearization circuit can provide linearity with greater independence from external control circuitry.

摘要： Circuitry, which includes a package interface, an RF amplification circuit, and a closed-loop phase linearization circuit, is disclosed. The package interface receives an RF signal and provides an amplified RF signal. The RF amplification circuit amplifies the RF signal to generate the amplified RF signal, such that an intermediate RF signal is generated during amplification of the RF signal. The closed-loop phase linearization circuit endogenously establishes a target phase of the amplified RF signal using the RF signal. Further, the closed-loop phase linearization circuit applies a phase-shift to the intermediate RF signal based on a difference between the target phase and a measured phase, which is representative of a phase of the amplified RF signal, wherein the phase-shift reduces phase distortion in the amplified RF signal.

摘要： A magnetic device producing a small amount of leakage flux and capable of substantially eliminating the amount of leakage flux that escapes the magnetic core of the device. The device includes at least a portion of an electronic circuit that includes an interphase transformer arranged on a magnetic core. The reactor windings on each leg of the magnetic core are disposed in close proximity to each other and can be wound concentrically or in a bifilar fashion. The resulting combination of the magnetic core and windings provides a high degree of magnetic coupling between reactor windings disposed on the same leg and between reactor windings disposed on differing legs. The high degree of magnetic coupling substantially reduces the amount of leakage flux that can affect other metal objects proximate the magnetic device.
