LMV243
Single-Channel, Quad-Band GSM Power Controller in
micro SMD
General Description
The device is intended for use within an RF transmit power
control loop in GSM mobile phones and supports GaAs HBT
and bipolar RF single supply power amplifiers. The circuit
operates with a single supply from 2.7V to 3.3V.
The LMV243 contains an RF detector, error amplifier, ramp
V/I converter and output driver. The LMV243 input interface
consists of the RF input, Ramp voltage, and a digital input to
perform the function ’Shutdown/Transmit Enable’. The de-
vice will be active in the case TX_EN = HI, otherwise, the
device goes into a low power consumption shutdown mode.
During shutdown the output will be in high impedance
(tri-state).
A single external RC combination is used to provide stable
operations that accommodates individual PA characteristics.
The LMV243 is offered in a 8-bump micro SMD 1.5mm x
1.5mm package. This space savings package supports flex-
ible product placement almost anywhere in the circuitboard.
