Abstract:
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.
