AWT6111

CDMA/AMPS Power Amplifier

Application Note - Rev 0

General Description

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.

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
