Abstract:
Embodiments of a circuit, system, and method are disclosed. A beam switch to a beam with a beam configuration from another beam with another beam configuration is detected. In response to the detected beam switch: a tuner setting is determined for an antenna tuner of an antenna element in an antenna array which transmits the first beam with the first beam configuration based on the first beam configuration, the tuner setting associated with the first beam configuration; and an indication of the tuner setting is provided to an impedance matching system of the antenna tuner to compensate for a mismatch between an impedance of the antenna element and impedance of one or more other radio frequency (RF) components of an RF front-end having the antenna element and antenna tuner.
