Abstract
Aspects of this disclosure relate to a multi-mode power amplifier system. A first power amplifier is configured to provide a radio frequency signal associated with a different radio access technology in a first mode than in a second mode. A second power amplifier is configured to be active in the first mode such that the first power amplifier and the second power amplifier are concurrently active in the first mode. A switch can electrically connect the output of the first power amplifier to different radio frequency signal path in the first mode than in the second mode. Related methods, power amplifier modules, and wireless communication devices are disclosed.

(canceled)
A power amplifier module comprising:
- a power amplifier having an output, the power amplifier configured to provide a radio frequency signal at the output in a dual connectivity mode and in a second mode, the radio frequency signal being associated with a first radio access technology in the dual connectivity mode and being associated with a second radio access technology in the second mode, the first radio access technology being different than the second radio access technology;
- and
- a switch configured to selectively electrically connect the output of the power amplifier to a first radio frequency signal path associated with the first radio access technology in the dual connectivity mode, and the switch configured to selectively electrically connect the output of the power amplifier to a second radio frequency signal path associated with the second radio access technology in the second mode.
A method of generating radio frequency signals, the method comprising:
- concurrently generating a first radio frequency signal with a first power amplifier and second radio frequency signal with a second power amplifier in a dual connectivity mode, the first power amplifier providing signal amplification associated with a first radio access technology in the dual connectivity mode;
- and
- activating the first power amplifier for radio frequency signal amplification in a second mode, the first power amplifier providing radio frequency signal amplification associated with a second radio access technology in the second mode, the second radio access technology being different than the first radio access technology, and the second power amplifier providing radio frequency signal amplification in the dual connectivity mode associated with a different radio access technology than the second radio access technology.
A power system comprising:
- a first power amplifier having a first output, the first power amplifier configured to provide a first radio frequency signal at the first output in a dual connectivity mode and in a second mode, the first radio frequency signal being associated with a first radio access technology in the dual connectivity mode and a second radio access technology in the second mode, the first radio access technology being different than the second radio access technology;
- a switch configured to selectively electrically connect the first output of the first power amplifier to a first radio frequency signal path associated with the first radio access technology in the dual connectivity mode, and the switch configured to selectively electrically connect the first output of the first power amplifier to a second radio frequency signal path associated with the second radio access technology in the second mode;
- and
- a second power amplifier configured to provide a second radio frequency signal associated with a third radio access technology in the dual connectivity mode, the third radio access technology being different than both the first radio access technology and the second radio access technology.
