ADI AD8364ACPZ-R2

Overview

The AD8364ACPZ-R2 is a true rms, responding, dual-channel RF powermeasurement subsystem for the precise measurement and controlof signal power. The flexibility of the AD8364ACPZ-R2 allows communicationssystems, such as RF power amplifiers and radio transceiverAGC circuits, to be monitored and controlled with ease. Operatingon a single 5 V supply, each channel is fully specified for operationup to 2.7 GHz over a dynamic range of 60 dB. The AD8364provides accurately scaled, independent, rms outputs of both RFmeasurement channels. Difference output ports, which measurethe difference between the two channels, are also available. Theon-chip channel matching makes the rms channel differenceoutputs extremely stable with temperature and process variations.The device also includes a useful temperature sensor with anaccurately scaled voltage proportional to temperature, specifiedover the device operating temperature range. The AD8364ACPZ-R2 canbe used with input signals having rms values from −55 dBm to+5 dBm referred to 50 Ω and large crest factors with noaccuracy degradation.

The AD8364ACPZ-R2 is supplied in a 32-lead, 5 mm × 5 mm LFCSP, forthe operating temperature of –40°C to +85°C.
