ADAPTIVE LINEARIZER |
| 摘要 |
An adaptive linearizer system includes an adaptive linearizer circuit that is configured to pre-distort an input signal based on one or more control signals to generate a pre-distorted signal, and a non-linear high-power amplifier (HPA) having non-linear characteristics that is coupled to the adaptive linearizer circuit. The nonlinear HPA amplifies the pre-distorted signal. The pre-distortion characteristics of the adaptive linearizer circuit provide for countering the non-linear characteristics of the non-linear HPA and compensating a non-linearity of the non-linear HPA. |

1. An adaptive linearizer system, the system comprising:
an adaptive linearizer circuit configured to pre-distort an input signal based on one or more control signals to generate a pre-distorted signal; and a non-linear high-power amplifier (HPA) having non-linear characteristics coupled to the adaptive linearizer circuit to amplify the pre-distorted signal, wherein pre-distortion characteristics of the adaptive linearizer circuit provide for countering the non-linear characteristics of the non-linear HPA and compensating a non-linearity of the non-linear HPA. |
