摘要： A method (600) and devices for enhancing the performance of one or more antennas (440) is provided. A control circuit (104) assesses performance of an antenna (101) in a plurality of bands, such as a receive band and a transmit band. The control circuit (104) can then adjust an adjustable impedance matching circuit (103) coupled to the antenna (101) to improve the efficiency of the antenna (101) in the selected band and can adjust a resonance of the antenna (101) to further improve an efficiency of the antenna (101) in the selected band. Operating parameters for the antenna (101) can be selected from one or more multi-dimensional lookup tables (120) where the parameters are indexed both to a first operating band (702) and a second operating band (703).

摘要： A radio frequency (RF) communication device comprises a first signal propagating circuit and a second signal propagating circuit, which together enables simultaneous transmission. The first signal propagating circuit is configured with a first tunable notch filter within a first transmit path and the second signal propagating circuit is configured with a second tunable notch filter within a second transmit path. A controller is communicatively coupled to a respective first tuning component and second tuning component of the tunable notch filters. The controller selectively tunes at least one of the tunable notch filters during signal propagation to produce a specific combined notch filtering response that reduces a level of IMD on at least one receive carrier frequency of at least one propagating signal. Aspects of the disclosure also provide a method for making the communication device.

摘要： Disclosed is a method (200) for charging energy storage devices. The method (200) can include a battery charging method in a power supply client connected by a data bus to a power supply host. The method (200) includes the steps of: detecting (210) a state of the power supply host; determining (220) a limit of current from the host to the client; allocating (230) a portion of the limit to a battery charging current; and charging (240) a battery of the client at the battery charging current such that the current from the host is greater than a recommended limit and less than or equal to the determined amount. Thus a client device can confidently charge at a rate which causes the port current to exceed a recommended limit, such as a USB port limit of 500 mA, when allowed by conditions of the host device. Advantageously, the method can help to expedite the charging time of a client battery, notwithstanding the number of other clients connected to the same host device for charging, thus minimizing the wait time of a user.

摘要： An amplifier which contains two amplifier stages. Each amplifier stage (433,435) utilizes a diode (407) to attenuate the RF input signal (401) and to stabilize the bias current over temperature. The two amplifier stages (433, 435) are cascaded together. The control voltage inputs are serially coupled through a transistor (423). The transistor (423) shifts the voltage of the control signal (425) down, thereby, shifting the control characteristics and AM characteristics of the first amplifier stage (435) relative to the second amplifier stage (433).

摘要： A method, transceiver integrated circuit (IC), and communications device for generating antenna tuning states derived from a pre-established trajectory of tuning states to adjust a detected signal level towards a preset, given value. A tuning state generation (TSG) controller determines whether a detected signal level matches a given value. If the detected signal level does not match the given value, the TSG controller selects an initial preset tuning state from a pre-established trajectory corresponding to a pre-identified operating condition that best matches a current operating condition. The TSG logic forwards the initial preset tuning state to the antenna tuner to trigger impedance transformation. Following generation of the initial preset tuning state, the controller receives an updated detected signal level. If the updated detected signal level fails to match the given value, the controller generates an incremental tuning state that is interpolated between the initial and a final preset tuning states.
