Power detection of individual carriers of aggregated carriers

Aspects of the present disclosure relate to detecting power associated with individual carriers of a carrier aggregated signal. In an embodiment, a carrier aggregation system includes a radio frequency (RF) source, a transmit output, and a directional coupler. RF sources, such as power amplifiers, may each be associated with a separate carrier. The transmit output may provide a carrier aggregated signal that includes aggregation of the separated carriers associated with the RF source. The directional coupler may provide an indication of RF power of one of the split carriers. 本公开的各方面涉及检测与载波聚合信号的单独载波相关联的功率。在实施例中，载波聚合系统包括射频(RF)源、发送输出和定向耦合器。诸如功率放大器的RF源每个可与分离载波相关联。所述发送输出可提供包括与所述RF源相关联的所述分离载波的聚合的载波聚合信号。所述定向耦合器可提供所述分离载波之一的RF功率的指示。
