100 MHz to 6 GHz TruPwr Detector Data Sheet ADL5500 FEATURES
The ADL5500 offers excellent temperature stability with near
True rms response
0 dB measurement error across temperature. The high accuracy
Excellent temperature stability
range, centered around +3 dBm at 900 MHz, offers ±0.1 dB
±0.1 dB accuracy vs. temperature over top 8 dB of input range
error from −40°C to +85°C over an 8.5 dB range. The ADL5500
Up to 30 dB input dynamic range at 3.9 GHz
reduces calibration requirements with low drift across a 30 dB
50 Ω input impedance
range over temperature and process variations.
1250 mV rms, +15 dBm, maximum input
The ADL5500 operates from −40°C to +85°C 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 RF transmitter or receiver power measurement 1 GENERAL DESCRIPTION
The ADL5500 is a mean-responding power detector for use in
OUTPUT (V)
high frequency receiver and transmitter signal chains from 100 MHz to 6 GHz. It is easy to apply, requiring only a single
0.1
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 input impedance of 50 Ω. The output is a linear-responding dc

voltage with a conversion gain of 6.4 V/V rms at 900 MHz. The
INPUT (dBm)
on-chip, 1 kΩ series resistance at the output combined 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.
