LTC5587IDD#PBF

LTC®5587 is a 10MHz to 6GHz, low power monolithic precision RMS power detector with an integrated 12bit serial analogue-to-digital converter (ADC). The RMS detector uses a proprietary technique to accurately measure the RF power of modulated signals with crest-factor as high as 12dB. The serial digital output of the detector is a 12bit word value that is directly proportional to the RF signal power measured in dBm. The LTC5587 is suitable for precision power measurement for a wide variety of RF standards, including LTE, WiMAX, W-CDMA, TD-SCDMA, CDMA, CDMA2000, EDGE, GSM, etc. This enables further filtering of the output modulation ripple using an off-chip capacitor before analogue-to digital conversion. Application includes LTE, WiMAX, W-CDMA, TD-SCDMA, CDMA, CDMA2000, EDGE, GSM, pico-cells, femto-cells RF power control, wireless repeaters, CATV/DVB transmitters, MIMO wireless access points, portable RMS power measurement, antenna monitor.
