GENERAL DESCRIPTION  
The ADL5501 is a mean-responding power detector for use  
in high frequency receiver and transmitter signal chains from  
50 MHz to 4 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  
input impedance of 50 Ω. The output is a linear-responding dc  
voltage with a conversion gain of 6.3 V/V rms at 900 MHz.  
The on-chip, 100 Ω series resistance at the output, combined  
with an external shunt capacitor, creates a low-pass filter response  
that reduces the residual ripple in the dc output voltage. For more  
complex waveforms, an external capacitor at the FLTR pin can  
be used for supplementary signal demodulation.  
The ADL5501 offers excellent temperature stability across a  
30 dB range and near 0 dB measurement error across temperature  
over the top portion of the dynamic range. In addition to its  
temperature stability, the ADL5501 offers low process variations  
that further reduce calibration complexity.  
The ADL5501 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.  
The ADL5501 operates from −40°C to +85°C and is available in  
a small 6-lead SC-70 package. It is fabricated on a proprietary  
high fT silicon bipolar process.
