The LMV243 is a single-channel, quad-band GSM power controller designed for use within an RF transmit power control loop in GSM mobile phones. It supports GaAs HBT and bipolar RF single supply power amplifiers. The circuit operates with a single supply voltage ranging from 2.7V to 3.3V. The LMV243 includes an RF detector, error amplifier, ramp V/I converter, and output driver. Its input interface consists of an RF input, ramp voltage, and a digital input for the 'Shutdown/Transmit Enable' function. The device is active when TX_EN = HI and goes into a low power consumption shutdown mode otherwise. During shutdown, the output is in high impedance (tri-state). The LMV243 utilizes a single external RC combination for stable operation, accommodating individual power amplifier characteristics. It is offered in an 8-bump micro SMD package measuring 1.5mm x 1.5mm x 0.995mm, allowing for flexible product placement on the circuit board.
