Abstract
Aspects of the disclosure relate to an apparatus for wireless communication. The apparatus may include a set of power detectors configured to generate a set of analog signals related to a set of output signal power levels of a set of transmit chains of a transmitter, respectively; an analog summer; a set of switching devices configured to send a selected one or more of the set of analog signals to the analog summer, and substantially isolated unselected one or more of the set of power detectors from the analog summer, wherein the analog summer is configured to generate a cumulative analog signal based on a sum of the selected one or more of the set of analog signals; an analog-to-digital converter (ADC) configured to generate a digital signal based on the cumulative analog signal; and a controller configured to control the set of switching devices.
