LMV243 Single-Channel, Quad-Band GSM Power Controller in micro SMD May 2002 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 device will be active in the case TX_EN = HI, otherwise, the device goes into a low power consumption shutdown mode.
