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

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.
