POWER AMPLIFIER WITH CASCODE SWITCHING OR SPLITTING FUNCTIONALITY |
| 摘要 |
Multiband power amplifier with cascode switching. A power amplification system can include a first transistor having a base configured to receive an input radio-frequency (RF) signal and having an emitter coupled to a ground potential. The power amplification system can include a plurality of second transistors. Each one of the plurality of second transistors can have a respective emitter coupled to a collector of the first transistor and can be configured to, when biased at a respective base, output an output RF signal at a respective collector. The power amplification system can further include a biasing circuit configured to bias one or more of the plurality of second transistors based on a control signal. |

1. A power amplification system comprising:
a first transistor having a base configured to receive an input radio-frequency (RF) signal and having an emitter coupled to a ground potential; a plurality of second transistors, each one of the plurality of second transistors having a respective emitter coupled to a collector of the first transistor and being configured to, when biased at a respective base, output an output RF signal at a respective collector; and a biasing circuit configured to bias one or more of the plurality of second transistors based on a control signal. |
