ADL5501AKSZ-R7

ADL5501 is a mean-responding TruPwr™ power detector for use in high frequency receiver and transmitter signal chains from 50MHz to 6GHz. It is easy to apply, requiring only a single supply between 2.7V and 5.5V and a power supply decoupling capacitor. The input is internally ac-coupled and has a nominal input impedance of 50 ohm. The output is a linear-responding dc voltage with a conversion gain of 6.3V/V rms at 900MHz. It is intended for true power measurement of simple and complex waveforms. The device is particularly useful for measuring high crest factor (high peak-to-rms ratio) signals, such as CDMA-, CDMA2000-, W-CDMA-, and QPSK-/QAM based OFDM waveforms. The on-chip modulation filter provides adequate averaging for most waveforms. Application includes measurement of CDMA-, CDMA2000-, W-CDMA-, and QPSK-/QAM-based OFDM, and other complex modulation waveforms, RF transmitter or receiver power measurement.
