MAX4473, Low-Cost / Low-Voltage / PA Power Control Amplifier
The MAX4473 PA power control IC is intended for closed-loop bias control of GSM power amplifiers.
The device facilitates accurate control of the current delivered to the power amplifier (PA) via a control voltage.
The error amplifier senses the voltage drop across an external current-sense resistor
