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.

Description

[0001] priority claim [0002] This patent application claims the title "ANTENNA POWER COUPLER HAVING A VARIABLE COUPLING FACTOR" filed on September 20, 2011 and is assigned to the assignee of the present application and is hereby expressly incorporated by reference herein. coupler)" U.S. Provisional Patent Application No. 61 / 537,020 priority interest. technical field [0003] This application relates generally to the operation and design of antenna systems for use with mobile devices, and more particularly to the design and operation of antenna power couplers. Background technique [0004] There is an increasing need to enable wireless devices to perform high quality transmission and reception over multiple frequency bands. Using multiple frequency bands provides increased data transmission speeds and / or increased services. Unfortunately, wireless devices need to perform power calibration for each frequency band. This results in increased calibration time. [0005] Anot...
