ADL5511ACPZ-R7

ADL5511ACPZ-R7 is a RF envelope and TruPwr™ rms detector. 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/V rms 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. Applications include RMS power and envelope detection of W-CDMA, CDMA2000, LTE, and other complex waveforms, drain modulation based power amplifier linearization, power amplifier linearization employing envelope-tracking methods.
