LTC4403-1/LTC4403-2  
Multiband RF Power  
Controllers for EDGE/TDMA  
U
FEATURES  
DESCRIPTIO  
The LTC®4403-2 is a multiband RF power controller for  
RF power amplifiers operating in the 300MHz to 2.4GHz  
range. TheLTC4403-2 has twooutputs tocontrol dual TX  
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.  
■
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  
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.  
■
Wide VIN 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  
■
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 TX PA or  
dual TX PA module with a single control input and is  
available in an 8-pin MSOP package.  
Low Operating Current: 1mA  
■
Low Shutdown Current: <10µA  
■
PCTL Input Filter  
■
Available in a 8-Pin MSOP Package (LTC4403-1)  
and 10-Pin MSOUP (LTC4403-2)  
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.
