FAN5904 Description
In High-Power Mode, GSM Tx power is enabled. In Low-Power Mode, up to 3.0 W is supported, enabling up to 29 dBm output power for 3G/3.5G and 4G platforms. The output voltage may be dynamically adjusted from 0.40 V to 3.50 V, proportional to an analog input voltage VCON ranging from 0.16 V to 1.40 V, optimizing poweradded efficiency.
