POWER AMPLIFIERS WITH SIGNAL CONDITIONING |
| 摘要 |
A device includes an amplifier having a first path and a second path and a first variable attenuator connected to the first path. The device includes a controller coupled to the first variable attenuator. The controller is configured to determine a magnitude of an input signal to the amplifier. When the magnitude of the input signal is below a threshold, the controller is configured to set an attenuation of the first variable attenuator to a first attenuation value. When the magnitude of the input signal is above the threshold, the controller is configured to set the attenuation of the first variable attenuator to a second attenuation value. The second attenuation value is less than the first attenuation value. |

1. A device, comprising:
an amplifier having a first path and a second path; a first variable attenuator connected to the first path; a controller coupled to the first variable attenuator, the controller being configured to:
determine a magnitude of an input signal to the amplifier,when the magnitude of the input signal is below a threshold, set an attenuation of the first variable attenuator to a first attenuation value, andwhen the magnitude of the input signal is above the threshold, set the attenuation of the first variable attenuator to a second attenuation value, the second attenuation value being less than the first attenuation value. |
