Abstract: Radio frequency (RF) duplexing devices and methods of operating the same are disclosed. In one embodiment, an RF duplexing device includes a transmission port, a receive port, a first duplexer, and a second duplexer. The first duplexer is coupled to the transmission port and the receive port, and is configured to provide a first phase shift from the transmission port to the receive port. The second duplexer is also coupled to the transmission port and the receive port. However, the second duplexer is configured to provide a second phase shift that is differential to the first phase shift from the transmission port to the receive port. By providing the second phase shift so that the second phase shift is differential to the first phase shift, the RF duplexing device can provide isolation through cancellation without needing to introduce significant insertion losses.

Abstract: Envelope power supply circuitry is operated in one of an off-state, a standby-state, and a transmit-state. In the standby-state, select components in envelope power converter circuitry in the envelope power supply circuitry are turned on in order to charge one or more inductive and/or capacitive elements therein to a maximum value necessary for supporting transmission of signals about a maximum output power. Accordingly, the envelope power supply circuitry is able to prepare to support transmission about any output power without knowing the output power ahead of time.

Abstract: A method for wireless charging power control is disclosed. In a wireless charging system, a wireless radio frequency (RF) charging signal transmitted by a wireless charging station is harvested and converted to a direct-current (DC) charging signal to charge a battery. To prevent overcharging damage to the battery, an effective charging power in the DC charging signal is measured and compared to a target charging power required by the battery. A battery charging signal indication (BCSI) is provided to the wireless charging station to decrease the effective charging power if the effective charging power is greater than the target charging power, or to increase the effective charging power if the effective charging power is less than the target charging power. By dynamically adjusting the effective charging power, it is possible to provide fast charging to the battery while protecting the battery from overcharging damage.
