AWT6111 CDMA/AMPS Power Amplifier Application Note - Rev 0 General Description The AWT6111 is a hetero-junction bipolar transistor (HBT) amplifier designed for the CDMA cellular handset. The frequency band of operation is 824-849 MHz. The AWT6111 is designed to operate from a single lithium-ion (Li-ion) battery. The amplifier input and output are matched to provide optimum performance in a 50 Ω system. Minimal external components are required for proper RF bypassing. The tantalum capacitors, C8 and C9, are not required. Landings should be made available on the printed circuit board (PCB) as a precaution.
