Linear-in-dB RMS Power Detector with  
35dB Dynamic Range  
FeaTures  
DescripTion  
The LTC®5596isa highaccuracy RMS powerdetectorthat  
provides a very wide RF input bandwidth, from 100MHz  
up to 40GHz. This makes the device suitable for a wide  
range of RF and microwave applications, such as point-  
to-point microwave links, instrumentation and power  
control applications.

The DC output voltage of the detector is an accurate rep-  
resentation of the average signal power applied to the RF  
input.Theresponseislinear-in-dBwith29mV/dBlogarith-

than 1dB accuracy. The detector is particularly suited for  
measurement of waveforms with crest factor (CF) as high  
as12dB, andwaveformsthatexhibitasignificantvariation

To achieve higher accuracy and lower output ripple, the  
averaging bandwidth can be externally adjusted by a ca-  
pacitor connected between the FLTR and OUT pins.
