Abstract
A radio frequency module includes a first power amplifier, a second power amplifier, a filter, a switch, and a matching circuit. The first power amplifier outputs a first amplified signal. The second power amplifier outputs a second amplified signal. The filter allows the first amplified signal and the second amplified signal to pass through. The switch has a first terminal and a second terminal. The first terminal is connected to an output portion of the first power amplifier. The second terminal is connected to the filter. The switch changes over connection and disconnection of the first terminal and the second terminal. The matching circuit is connected between an output portion of the second power amplifier and a signal path between the second terminal of the switch and the filter.
Claims10
A radio frequency module, comprising:
- a first power amplifier configured to amplify a first signal and to output a first amplified signal;
- a second power amplifier configured to amplify a second signal with an amplification factor smaller than an amplification factor of the first power amplifier, and to output a second amplified signal;
- a filter configured to pass the first amplified signal and the second amplified signal;
- a switch having a first terminal connected to an output of the first power amplifier and a second terminal connected to the filter, and configured to change connection and disconnection of the first terminal and the second terminal;
- and
- a matching circuit connected between an output of the second power amplifier and a first signal path, the first signal path being between the second terminal of the switch and the filter,
- wherein the switch is not in a signal path between the output of the second power amplifier and the filter.
