GENERAL DESCRIPTION  
The AD8364 is a true rms, responding, dual-channel RF power  
measurement subsystem for the precise measurement and control  
of signal power. The flexibility of the AD8364 allows communi-  
cations systems, such as RF power amplifiers and radio transceiver  
AGC circuits, to be monitored and controlled with ease. Operating  
on a single 5 V supply, each channel is fully specified for operation  
up to 2.7 GHz over a dynamic range of 60 dB. The AD8364  
provides accurately scaled, independent, rms outputs of both RF  
measurement channels. Difference output ports, which measure  
the difference between the two channels, are also available. The  
on-chip channel matching makes the rms channel difference  
outputs extremely stable with temperature and process variations.  
The device also includes a useful temperature sensor with an  
accurately scaled voltage proportional to temperature, specified  
over the device operating temperature range. The AD8364 can  
be used with input signals having rms values from −55 dBm to  
+5 dBm referred to 50 Ω and large crest factors with no  
accuracy degradation.  
Integrated in the AD8364 are two matched AD8362 channels  
(see the AD8362 data sheet for more information) with improved  
temperature performance and reduced log conformance ripple.  
Enhancements include improved temperature performance and  
reduced log-conformance ripple compared to the AD8362. On-  
chip wide bandwidth output op amps are connected to accom-  
modate flexible configurations that support many system  
solutions.  
The device can easily be configured to provide four rms  
measurements simultaneously. Linear-in-dB rms measurements  
are supplied at OUTA and OUTB, with conveniently scaled  
slopes of 50 mV/dB. The rms difference between OUTA and  
OUTB is available as differential or single-ended signals at  
OUTP and OUTN. An optional voltage applied to VLVL  
provides a common mode reference level to offset OUTP and  
OUTN above ground.  
The AD8364 is supplied in a 32-lead, 5 mm × 5 mm LFCSP, for  
the operating temperature of –40°C to +85°C.
