Dual Output

GSM PA Controller

AD8316

FEATURES

Complete RF Detector/Controller Function

Selectable Dual Outputs

49 dB Range at 0.9 GHz (–47.6 dBm to +1.5 dBm re 50 ꢀ)

Accurate Scaling from 0.1 GHz to 2.5 GHz

Temperature-Stable Linear-in-dB Response

Log Slope of 22 mV/dB

True Integration Function in Control Loop

Low Power: 23 mW at 2.7 V

power control signal is required for each band. The logarithmic

amplifier technique provides a much wider measurement range

and better accuracy than is possible using controllers based on

diode detectors. In particular, multiband and multimode cellu-

lar designs can benefit from the temperature-stable (–30°C to

+85°C) operation over all cellular telephony frequencies.

Its high sensitivity allows control at low input signal levels, thus

reducing the amount of power that needs to be coupled to the

detector. The selected output, OUT1 or OUT2, has the voltage

range and current drive to directly connect to the gain control

pin of most handset power amplifiers; the deselected output is

pulled low to ensure that the inactive PA remains off. Each

output has a dedicated integrating filter capacitor that allows

separate control loop settings for each PA. OUT1 and OUT2 can

swing from 125 mV above ground to within 100 mV below the

supply voltage. Load currents of up to 12 mA can be supported.

Power-Down to 11 ꢁW

APPLICATIONS

Single-Band, Dual-Band, and Triband Mobile Handsets

(GSM, DCS, PCS, EDGE)

Wireless Terminal Devices

Transmitter Power Control

The setpoint control input applied to pin VSET has an operating

range of 0.25 V to 1.4 V. The input resistance of the setpoint

interface is over 100 MΩ, and the bias current is typically 0.5 µA.

GENERAL DESCRIPTION

The AD8316 is a complete, low cost subsystem for the precise

control of dual RF power amplifiers (PAs) operating in the

frequency range 0.1 GHz to 2.5 GHz and over a typical dynamic

range of 50 dB. The device is a dual-output version of the AD8315

and intended for use in dual-band or triband cellular handsets

and other battery-operated wireless devices where a separate

The AD8316 is available in 10-lead MSOP and 16-lead LFCSP

packages and consumes 8.5 mA from a 2.7 V to 5.5 V supply.

When it is powered down, the sleep current is 4 µA.
