LMV242 Dual Output, Quad-Band GSM/GPRS Power Amplifier Controller

Check for Samples: LMV242

FEATURES

DESCRIPTION

The LMV242 is a power amplifier (PA) controller

intended for use within an RF transmit power control

loop in GSM/GPRS mobile phones. The LMV242

supports all single-supply PA’s including InGaP, HBT

and bipolar power amplifiers. The device operates

with a single supply from 2.6V to 5.5V.

•

Support of InGaP HBT, Bipolar Technology

Quad-Band Operation

Shutdown Mode for Power Save in R_XSlot

Integrated Ramp Filter

50 dB RF Detector

Included in the PA controller are an RF detector, a

ramp filter and two selectable output drivers that

function as error amplifiers for two different bands.

The LMV242 input interface consists two analog and

two digital inputs. The analog inputs are the RF input,

Ramp voltage input. The digital inputs perform the

function of “Band Select” and “Shutdown/Transmit

Enable” respectively. The “Band Select” function

enables either of two outputs, namely OUT1 when BS

= High, or output OUT2 when BS = Low. The output

that is not enabled is pulled low to the minimum

output voltage. The LMV242 is active in the case

TX_EN = High. When TX_EN = Low the device is in

a low power consumption shutdown mode. During

shutdown both outputs will be pulled low to the

minimum output voltage. Individual PA characteristics

are accommodated by a user selectable external RC

combination.

GPRS Compliant

External Loop Compensation Option

Accurate Temperature Compensation

WSON Package 3x3 mm and Fully Tested Die

Sales

APPLICATIONS

•

GSM/GPRS/TDMA/TD_SCDMA Mobile Phone

Pulse RF Control

Wireless LAN

GSM/GPRS Power Amplifier Module

Transmit Module

The LMV242 is offered in fully tested die form as well

as in a 10-lead WSON package and is therefore

especially suitable for small footprint PA module

solutions.
