1 Figure 1. Functional Block Diagram 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 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 …
