100 MHz to 6 GHz TruPwr Detector Data Sheet ADL5500 The ADL5500 offers excellent temperature stability with near FEATURES 0 dB measurement error across temperature. The high accuracy True rms response range, centered around +3 dBm at 900 MHz, offers 0.1 dB Excellent temperature stability error from 40C to +85C over an 8.5 dB range. The ADL5500 0.1 dB accuracy vs. temperature over top 8 dB of input range reduces calibration requirements with low drift across a 30 dB Up to 30 dB input dynamic range at 3.9 GHz range over temperature and process variations. 50 input impedance 1250 mV rms, +15 dBm, maximum input The ADL5500 operates from 40C to +85C and is available in Single-supply operation: 2.7 V to 5.5 V a 4-ball, 1.0 mm 1.0 mm wafer-level chip scale package. It is Low power: 3 mW at 3 V supply fabricated on a proprietary high fT silicon bipolar process. RoHS compliant 5 APPLICATIONS Measurement of CDMA2000, W-CDMA, and QPSK-/QAM- based OFDM, and other complex modulation waveforms 1 RF transmitter or receiver power measurement GENERAL DESCRIPTION The ADL5500 is a mean-responding power detector for use in high frequency receiver and transmitter signal chains from 0.1 100 MHz to 6 GHz. It is easy to apply, requiring only a single supply between 2.7 V and 5.5 V and a power supply decoupling capacitor. The input is internally ac-coupled and has a nominal 0.03 input impedance of 50 . The output is a linear -responding dc 25 20 15 10 5 0 5 10 15 voltage with a conversion gain of 6.4 V/V rms at 900 MHz. The INPUT (dBm) on-chip, 1 k series resistance at the output com bined with an Figure 1. Output vs. Input Level, Supply 3 V, Frequency 1.9 GHz external shunt capacitor creates a low-pass filter response that reduces the residual ripple in the dc output voltage. The ADL5500 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 CDMA2000, W-CDMA, and QPSK/QAM-based OFDM waveforms.
