DEVICES AND METHODS THAT FACILITATE POWER AMPLIFIER OFF STATE PERFORMANCE |
| 摘要 |
A peaking amplifier is disclosed. The peaking amplifier includes a driver stage, a final stage, and an interstage matching network. The driver stage has a load impedance and is configured to generate a driver output based on an input signal. The final stage has a final stage input impedance and is configured to generate a peaking output based on the driver output. The interstage matching network is coupled to the driver stage and the final stage. The interstage matching network is configured to transform the final stage input impedance to the load impedance for the driver stage when the peaking amplifier is ON and to provide a short to an input of the final stage when the peaking amplifier is in an OFF state. |

1. A peaking amplifier comprising:
a driver stage having a load impedance and configured to generate a driver output based on an input signal; a final stage having a final stage input impedance and configured to generate a peaking output based on the driver output; and an interstage matching network coupled to the driver stage and the final stage and configured to transform the final stage input impedance to the load impedance for the driver stage when the peaking amplifier is in an ON state and provide a short to an input of the final stage when the peaking amplifier is in an OFF state. |
