ADL5511ACPZ-R7

The ADL5511ACPZ-R7 is a RF Envelope and TruPwr™ RMS Detector operating from DC to 6GHz. The envelope output voltage is presented as a voltage that is proportional to the envelope of the input signal. The RMS output voltage is independent of the peak-to-average ratio of the input signal. The RMS output is a linear-in-V/V voltage with a conversion gain of 1.9V/Vrms at 900MHz. The envelope output has a conversion gain of 1.46V/V at 900MHz and is referenced to an internal 1.1V reference voltage, which is available on the EREF pin. The ADL5511 can operate from DC to 6GHz on signals with envelope bandwidths up to 130MHz. The extracted envelope can be used for RF power amplifier (PA) linearization and efficiency enhancements and the RMS output can be used for RMS power measurement. The high RMS accuracy and fast envelope response are particularly useful for envelope detection and power measurement of broadband, high peak-to-average signals that are used in CDMA2000, W-CDMA and LTE syste
