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:
a first amplifier connected to a first path; a second amplifier connected to a second path; a variable attenuator connected to the second path; and a controller configured to:
determine whether the first amplifier is at saturation, andwhen the first amplifier is not at saturation, set an attenuation of the variable attenuator to a first attenuation value to force the second amplifier into a non-conducting condition. |
