GENERAL DESCRIPTION

The

AD8361

is a mean-responding power detector for use in

high frequency receiver and transmitter signal chains, up to

2.5 GHz. It is very easy to apply. It requires a single supply only

between 2.7 V and 5.5 V, a power supply decoupling capacitor,

and an input coupling capacitor in most applications. The

output is a linear-responding dc voltage with a conversion gain

of 7.5 V/V rms. An external filter capacitor can be added to

increase the averaging time constant.

V rms (Volts)

The

AD8361

is intended for true power measurement of simple

and complex waveforms. The device is particularly useful for

measuring high crest-factor (high peak-to-rms ratio) signals,

such as CDMA and W-CDMA.

The

AD8361

has three operating modes to accommodate a

variety of analog-to-digital converter requirements:

GROUND

REFERENCE MODE

Ground reference mode, in which the origin is zero.

Internal reference mode, which offsets the output 350 mV

above ground.

Supply reference mode, which offsets the output to V

/7.5.

(6-Lead SOT-23 Package Ground Reference Mode Only)

The

AD8361

is specified for operation from −40°C to +85°C

and is available in 8-lead MSOP and 6-lead SOT-23 packages. It

is fabricated on a proprietary high f

silicon bipolar process.
