COMPRESSION CONTROL OF CASCODE POWER AMPLIFIERS |
| 摘要 |
Compression control of cascode power amplifiers. A power amplifier module can include a power amplifier including a cascode transistor pair. The cascode transistor pair can include a first transistor and a second transistor. The power amplifier module can include a current comparator configured to compare a first base current of the first transistor and a second base current of the second transistor to generate a comparison signal. The power amplifier module can include a saturation controller configured to maintain the power amplifier out of saturation based on the comparison signal. |

1. A power amplifier module comprising:
a power amplifier including a cascode transistor pair, the cascode transistor pair including a first transistor and a second transistor; a current comparator configured to compare a first base current of the first transistor and a second base current of the second transistor to generate a comparison signal; and a saturation controller configured to maintain the power amplifier out of saturation based on the comparison signal. |
