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

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.
