| 摘要: |
| 低噪声微波晶体管通常要求具有最小的噪声系数及相应的增益(一般O.5～1.5分贝,小于晶体管的最大有效增益).这可通过调节放大器,牺牲一点噪声系数来获得最佳的性能. |

| Abstract: |
| Low-noise microwave transistors are usually specifiedas having a minimum noise figure and an associated gain.However, the associated gain is usually 0.5 to 1.5 dBless than the transistor's maximum available gain. Designers can adiust amplifiers for optimum performance by trading noise figue for gain. |
