TUNABLE FILTER FEEDBACK TO CONTROL ANTENNA SWITCH DIVERSITY

摘要

A method, antenna switching integrated circuit (IC), and communications device that connect a transmitter to a selected antenna to propagate at least one transmission signal to the selected one of at least two antennas, based on feedback information associated with one or more antennas. An antenna tuning and switching (ATS) controller receives feedback information about a current status of an antenna tuner, wherein the current status of the antenna tuner is either locked or unlocked. In response to the current status of the antenna tuner being in a locked state, the ATS controller triggers an antenna selection switch to connect the antenna (that is associated with the antenna tuner) to the transmitter in order to propagate the transmission signal(s) from the transmitter to the antenna. If the antenna tuner is in an unlocked state, the ATS controller selects a different antenna that is not associated with an antenna tuner.
