LTC4403-1/LTC4403-2

Multiband RF Power

Controllers for EDGE/TDMA

FEATURES

DESCRIPTIO

Supports AM Modulation in EDGE/TDMA (ANSI-136)

Applications

Single Output RF Power Amplifier Control

(LTC4403-1)

Dual Output RF Power Amplifier Control (LTC4403-2)

Internal Schottky Diode Detector with >40dB Range

Wide Input Frequency Range: 300MHz to 2.4GHz

Autozero Loop Cancels Offset Errors and

Temperature Dependent Offsets

Wide V

Range: 2.7V to 6V

Allows Direct Connection to Battery

RF Output Power Set by External DAC

Internal Frequency Compensation

Rail-to-Rail Power Control Outputs

Low Operating Current: 1mA

Low Shutdown Current: < 10µA

PCTL Input Filter

Available in a 8-Pin MSOP Package (LTC4403-1)

and 10-Pin MSOP (LTC4403-2)

The LTC

4403-2 is a multiband RF power controller for

RF power amplifiers operating in the 300MHz to 2.4GHz

range. The LTC4403-2 has two outputs to control dual T

PA modules with two control inputs. An internal sample

and hold circuit enables the LTC4403-2 to be used with

AM modulation via the carrier or PA supply. The input

voltage range is optimized for operation from a single

lithium-ion cell or 3× NiMH.

RF power is controlled by driving the RF amplifier power

control pins and sensing the resultant RF output power.

The RF sense voltage is peak detected using an on-chip

Schottky diode. This detected voltage is compared to the

DAC voltage at the PCTL pin to control the output power.

The LTC4403-1 is a single output RF power controller

with identical performance to the LTC4403-2. The

LTC4403-1 has one output to control a single T

PA or

dual T

PA module with a single control input and is

available in an 8-pin MSOP package.

Internal and external offsets are cancelled over tempera-

ture by an autozero control loop. The shutdown feature

disables the part and reduces the supply current to

< 10µA.
