Description

The LMV243 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 device 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 flexible product placement almost anywhere in the circuitboard.
