LMV248 dual band GSM power controller
The LMV248 is an RF power amplifier controller designed for simple implementation of transmit power control loops in GSM and DCS/PCN mobile phones. It supports both GaAs HBT and bipolar RF power amplifiers and operates from a single supply of 2.5V to 5V. The device integrates an error amplifier with an input summing network, input and output band switches, input filters, and output drivers to replace multiple discrete parts.
