Agilent ACPM-7891
Tri-Band Power Amplifier Module
EGSM, DCS and PCS Multi-slot GPRS
Data Sheet
Description
The ACPM-7891 is a fully
matched tri-band EGSM/DCS/
PCS power amplifier module
designed on Agilent Technologies’
leading edge Enhancement Mode
PHEMT (E-pHEMT) process.
The ACPM-7891 has the highest
Power-added Efficiency (PAE) for
all three bands of operation in
the industry, enabling customers
to design handset, PDA and data
card with up to 15% longer
transmit or talk time.
The Agilent ACPM-7891 provides
a cost effective dual or tri-band
GSM PA solution with the addi-
tional benefit of excellent effi-
ciency enabling multi-slot GPRS
operation and extended transmit
time. The device is internally
matched to 50Ω and therefore an
effective design can be imple-
mented quickly with a few
additional capacitors for d.c.
blocking of the output ports and
bypassing of the supply pins.
