GENERAL DESCRIPTION  
The AD8363 is a true RMS responding power detector that has  
more than 50 dB measurement range when driven with a  
single-ended 50 Ω source. The device provides a solution in a  
variety of high frequency communication systems, and in  
instrumentation, requiring an accurate response to signal  
power. The AD8363 is easy to use with its single-ended 50 Ω  
input, only requiring a single 5 V supply, and a few capacitors.  
The AD8363 can operate from arbitrarily low frequencies to 6  
GHz and can accept inputs that have RMS values from less than  
-50 dBm to at least 0 dBm, with large crest factors, exceeding  
the requirements for accurate measurement of WiMAX,  
WCDMA, and CDMA signals.  
Used as a power measurement device, VOUT is connected to  
VSET. The output is then proportional to the logarithm of the  
RMS value of the input. In other words, the reading is  
presented directly in decibels and is conveniently scaled 1 V per  
decade, or 50 mV/dB; other slopes are easily arranged. In  
controller mode, the voltage applied to VSET determines the  
power level required at the input to null the deviation from the  
set point. The output buffer can provide high load currents.  
The AD8363 has 1.5 mW power consumption when powered  
down by a logic high applied to pin 1, TCM2. It powers up  
within about 30 μs to its nominal operating current of 60 mA at  
25°C. The AD8363 is supplied in a 4 mm x 4 mm, 16-lead  
LFCSP for operation over the temperature range of −40°C to  
+125°C. An evaluation board is available.  
The AD8363 can determine the true power of a high frequency  
signal having a complex low frequency modulation envelope, or  
can be used as a simple low frequency RMS voltmeter. The  
high-pass corner generated by its internal offset-nulling loop  
can be lowered by a capacitor added on the CHPF pin.
