Product Summary

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

communications 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.
