Abstract
Aspects of this disclosure relate to detecting power associated with an individual carrier of a carrier aggregated signal. In an embodiment, a carrier aggregation system includes radio frequency (RF) sources, a transmission output, and a directional coupler. The RF sources, such as power amplifiers, can each be associated with a separate carrier. The transmission output can provide a carrier aggregated signal that includes an aggregation of the separate carriers associated with the RF sources. The directional coupler can provide an indication of RF power of one of the separate carriers.
Claims23
A carrier aggregation system comprising:
- radio frequency sources, each of the radio frequency sources being associated with a separate carrier;
- a frequency multiplexing circuit configured to perform frequency domain multiplexing, the frequency multiplexing circuit including a terminal configured to provide a carrier aggregated signal, the carrier aggregated signal including an aggregation of the separate carriers associated with the radio frequency sources;
- and
- a directional coupler arranged such that the frequency multiplexing circuit is in a signal path between the radio frequency sources and the directional coupler.
A carrier aggregation system comprising:
- radio frequency sources, each of the radio frequency sources being associated with a separate carrier;
- a frequency multiplexing circuit configured to perform frequency domain multiplexing, the frequency multiplexing circuit including a terminal configured to provide a carrier aggregated signal, the carrier aggregated signal including an aggregation of the separate carriers associated with the radio frequency sources;
- a directional coupler configured to provide an indication of radio frequency power of a first individual carrier of the separate carriers;
- and
- a multi-throw switch configured to selectively provide the indication of radio frequency power from the directional coupler to a power detector.
A power amplifier system with carrier aggregation, the power amplifier system comprising:
- power amplifiers including at least a first power amplifier associated with a first carrier and a second power amplifier associated with a second carrier, the first carrier and the second carrier being radio frequency signals;
- a frequency multiplexing circuit configured to perform frequency domain multiplexing, the frequency multiplexing circuit including a terminal configured to provide a carrier aggregated signal that includes an aggregation of at least the first carrier and the second carrier;
- a band pass filter coupled between the first power amplifier and the frequency multiplexing circuit;
- and
- a directional coupler in a signal path between the first power amplifier and the band pass filter, the directional coupler configured to provide an indication of power of an individual carrier of the aggregated carrier, the individual carrier being one of the first carrier or the second carrier.
