摘要： The present disclosure relates to transmission circuitry of a wireless communication device. The transmission circuitry includes power amplifier circuitry, an output matching network, and impedance control circuitry. The power amplifier circuitry amplifies a radio frequency (RF) input signal to provide an amplified RF output signal, which is passed through the output matching network and transmitted via one or more antennas. As the center frequency of the RF input signal and conditions of operating parameters change, the impedance control circuitry adjusts the values of one or more variable impedance elements of the output matching network in a desired fashion. The values of the variable impedance elements are adjusted such that the output matching network concurrently and dynamically presents the desired load impedances at the center frequency and at one or more harmonics of the RF input signal to achieve a given performance specification.

摘要： An adaptive matching RF architecture and an associated matching method are provided. The RF architecture comprises a power amplifier module, a receiving module, an antenna, an RF processing module, a baseband control module and at least one adjustable matching network module, the at least one adjustable matching network module being connected between the power amplifier module and the RF processing module, and/or between the receiving module and the RF processing module, and/or between the antenna and the RF processing module. The baseband control module is pre-stored with multiple matching values corresponding to multiple different application scenarios, the matching values of the at least one adjustable network module being applied based on the application scenarios to attain the optimum RF performance. By the above means, variable matching network technologies are applied to replace the traditional fixed matching network, enabling the network to adaptively adjust values of the matching networks based on different working conditions, and finally achieving the optimum performance at various frequency points under various working conditions.

摘要： A load impedance decision device, a wireless power transmission device, and a wireless power transmission method are provided. At least one of a distance and an angle between two resonators may be measured. A load impedance may be determined based on at least one of the measured distance and the measured angle. When the distance between the two resonators changes, a high power transfer efficiency may be maintained without using a separate matching circuit. Where the load impedance is determined, a test power may be transmitted. Depending on a power transfer efficiency of the test power, the load impedance may be controlled and power may be wirelessly transmitted from the source resonator to the target resonator.
