Antenna power coupler having a variable coupling factor |
| 摘要 |
An antenna power coupler having a variable coupling factor is disclosed. In an exemplary embodiment, an apparatus includes a coupler configured to generate a power detection signal based on transmit signal power associated with a plurality of transmission technologies and a variable attenuator configured to apply a selected attenuation factor to the power detection signal to generate an adjusted power detection signal, the selected attenuation factor associated with a selected transmission technology. |

1. Apparatus comprising:
a coupler configured to generate a power detection signal based on transmit signal power associated with a plurality of transmission technologies; a variable attenuator configured to apply a selected attenuation factor to the power detection signal to generate an adjusted power detection signal that is maintained below a fixed threshold level, the selected attenuation factor is applied by the variable attenuator during all transmit signal powers associated with a selected transmission technology; and a detection receiver configure to retrieve the selected attenuation factor from a memory based on the selected transmission technology and input the selected attenuation factor to the variable attenuator. |
