AWT6107 EGSM/DCS Dual Band 3.5V GPRS Power Amplifier Module Advanced Product Information Rev. 1, January 2001 FEATURES · · · · · · · · · · InGaP HBT Technology High Efficiency 55% EGSM High Efficiency 50% DCS Low Leakage Current (5mA) SMT Module Package Small Footprint (9.2mm X 11.6mm) Low Profile (1.55 mm) 50W Input and Output Matching Minimal Number of External Components GPRS Capable (2 TX Slots) APPLICATIONS · · EGSM/DCS Dual Band Handsets/PDA GPRS Class 10 9.2x11.6 mm MCM Module Package 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.

These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of this data sheet. Exposure to maximum ratings for extended periods can adversely affect device reliability.
