Abstract: An apparatus is disclosed for waveform-tailored average power tracking. In an example aspect, the apparatus includes an amplifier, a power converter, and an average power tracking module. The amplifier is configured to amplify radio-frequency signals using a supply voltage. The radio-frequency signals have different waveforms. The power converter is coupled to the amplifier and configured to provide the supply voltage. The average power tracking module is coupled to the power converter and configured to adjust the supply voltage according to the different waveforms to cause the supply voltage to vary across at least two waveforms of the different waveforms for related average output powers.

Abstract: Certain aspects of the disclosure related to communications apparatus provides isolation between wireless protocols when operating currently while incurring the additional insertion loss based on providing the isolation only when needed. In an aspect, an apparatus include a switched filter coupled to an antenna where the switched filter includes a filter and a bypass line along with switching circuitry configured to selectively establish a bypass signal path including the bypass line or a filtered signal path including the filter. The apparatus further includes a switched filter controller configured to cause the switching circuitry to selectively connect a transceiver unit to the antenna via the bypass signal path or via the filtered signal path based at least on a frequency band of a carrier signal and a bandwidth of the carrier signal.

Abstract: In certain aspects, a system includes a first filter, a second filter, a dummy load, and a switching circuit coupled to the first filter, the second filter, and the dummy load, and coupled to a first antenna and a second antenna. In a first mode, the switching circuit couples the first filter and the second filter to the first antenna, and, in a second mode, the switching circuit couples the first filter and the third filter to the first antenna and couples the second filter to the second antenna. In certain aspects, the dummy load includes a third filter.

Abstract: Aspects of the present disclosure provide signal amplification. An example method generally includes amplifying a version of a first input signal with a power amplifier in a first state where a bias voltage of the power amplifier is set to a first voltage based on a first tracking mode; obtaining a first output signal of the power amplifier in a second state where the bias voltage is set to a second voltage less than the first voltage; determining a predistortion associated with the power amplifier based at least in part on the obtained first output signal; applying the predistortion to the first input signal; and amplifying a version of the predistorted first input signal with the power amplifier in a third state where the bias voltage is set to a third voltage based on a second tracking mode, wherein the third voltage is less than the first voltage.

Abstract: Certain aspects of the present disclosure provide object detection based on perturbations in a channel model over time. An example portable apparatus includes a primary antenna, a secondary antenna, a transmit path, a radio frequency (RF) coupler, and a receive path. The transmit path is coupled to the primary antenna and configured to output a transmit signal for transmission via the primary antenna. The RF coupler is coupled to the secondary antenna. The receive path has an input selectively coupled between the transmit path and the RF coupler such that when the receive path is coupled to the RF coupler and configured to operate concurrently with the transmit path, the receive path is configured to receive a reflected portion of the transmit signal from an object located in proximity to the portable apparatus.
