1. A method of power detection in a carrier aggregation system, the method comprising:
generating a time division duplexing carrier aggregated signal, the time division duplexing carrier aggregated signal including a time division duplexing aggregation of at least a first carrier associated with a first power amplifier and a second carrier associated with a second power amplifier;
detecting, using a directional coupler in a signal path between a frequency multiplexing circuit and an antenna, an indication of power of the first carrier; and
detecting, using the directional coupler, an indication of power of the second carrier.
