Description
The AWT6107 power amplifier module has been optimized for dual band operation (EGSM and DCS1800
bands). The amplifier is suitable for class 10 GPRS (2 TX Slots) handsets and similar communication
systems. The module integrates practically all circuitry associated with the power amplifier function including
bias management and matching components for 50W systems. This includes closed loop over control
voltage protection making the amplifier extremely rugged. The maximum output power is achieved at a lower
control voltage avoiding the need to use rail to rail operational amplifiers in the power control scheme.
The module uses a two stage EGSM power amplifier and a three stage DCS1800 power amplifier. Both
power amplifier outputs have VCC present at the output and require DC blocks when interfacing with other
circuitry. The input signals have internal DC blocking and require no additional components.
