COMPRESSION CONTROL THROUGH POWER AMPLIFIER LOAD ADJUSTMENT |
摘要 |
Compression control through power amplifier load adjustment. 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 power amplifier bias controller including a current comparator configured to compare a first base current of the first transistor and a second base current of the second transistor to obtain a comparison value. The power amplifier module can include a saturation controller configured to supply a reference signal to an impedance matching network based on the comparison value. The impedance matching network can be configured to modify a load impedance of a load line in electrical communication with the power amplifier based at least in part on the reference 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 power amplifier bias controller including a current comparator configured to compare a first base current of the first transistor and a second base current of the second transistor to obtain a comparison value; and a saturation controller configured to supply a reference signal to an impedance matching network based on the comparison value, the impedance matching network being configured to modify a load impedance of a load line in electrical communication with the power amplifier based at least in part on the reference signal. |
