AN-1375 Linear-In-dB RF Power Detector In W-CDMA User Equipment (Rev. A)
PDF, 924 Kb, Revision: A, File published: Apr 30, 2013
Since most of the deployed W-CDMA networks use FDD mode only and the W-CDMA FDD has fastclosed-loop power control in both uplink and downlink, hardware implementation for RF power detection indownlink from user equipment to base station is needed in order to meet the required air interfacestandard. This application report suggests application subsystem circuits for use in closed-loop power
