Abstract: A transceiver is configured for a calibration mode of operation in which an impedance of a transmit chain is tuned responsive to a power measurement of a mixed RF calibration signal to form a tuned transmit chain. A direct conversion mixes an RF calibration signal with a DC offset signal to form the mixed calibration signal. During a normal mode of operation, a heterodyne mixer mixes an LO signal with an IF signal to produce an RF signal that is amplified through the tuned transmit chain.

Abstract: An antenna system includes: a ground conductor; a substrate; a pair of planar dipole conductors disposed such that at least a portion of the substrate is disposed between the ground conductor and the pair of dipole conductors; a pair of energy couplers each electrically connected to a respective one of the pair of dipole conductors; and a pair of isolated lobes including electrically-conductive material. The pair of isolated lobes are electrically separate from the pair of dipole conductors and the pair of energy couplers, and disposed between the pair of dipole conductors and the ground conductor.

Abstract: Certain aspects of the present disclosure provide systems and methods for performing a power amplifier characterization. One example method generally includes determining, by a user equipment, if a condition associated with a power amplifier characterization is met. In certain aspects, the method includes determining, by the user equipment, a calibration gap after the condition is met. The method also includes performing, by the user equipment, the power amplifier characterization of the one or more power amplifiers of the user equipment during the calibration gap.

Abstract: Certain aspects are directed to an apparatus configured for wireless communication. The apparatus may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the one or more processors are configured to cause the apparatus to obtain a sample of an analog signal. In some examples, the one or more processors are configured to cause the apparatus to output the sample to an analog-to-digital converter (ADC) via one of at least a first path or a second path based at least in part on whether the sample satisfies a first threshold condition or a second threshold condition.

The apparatus may include at least one transmit chain configured to operate within a first frequency band and at least one receive chain configured to operate within a second frequency band. The apparatus may receive coordination information that is configured to mitigate the self-interference between the at least one transmit chain of the apparatus and the at least one receive chain of the apparatus. In some examples, the received coordination information includes at least one of subcarrier spacing coordination information, beam coordination information, or slot format index coordination information. In some examples, the apparatus may transmit a first signal while receiving a second signal based on at least the subcarrier spacing coordination information, the beam coordination information, or the slot format index coordination information to mitigate self-interference.
