ANTENNA POWER COUPLER HAVING VARIABLE COUPLING FACTOR

摘要

PROBLEM TO BE SOLVED: To provide an antenna power coupler having a variable coupling factor for use in a mobile device.SOLUTION: An apparatus 200 includes: a coupler 214 configured to generate a power detection signal on the basis of transmit signal power associated with a plurality of transmission technologies; and a variable attenuator 216 configured to apply a selected attenuation factor to the power detection signal to generate an adjusted power detection signal. The selected attenuation factor is associated with a selected transmission technology.
