Description
The ACPM-7821 is a CDMA (Code Division Multiple
Access) power amplifier module designed for hand-
sets operating in the 898–925MHz bandwidth. The
ACPM-7821 meets stringent CDMA linearity require-
ments up to 28 dBm output power.
Features
• Excellent linearity
• High efficiency
• 10-pin surface mounting package
(4 mm x 4 mm x 1.1 mm)
A low current (Vcont) pin is provided for high effi-
ciency improvement of the low output power range.
The ACPM-7821 features CoolPAM circuit technology
offering state-of-the-art reliability, temperature
stability and ruggedness.
• Low quiescent current
• Internal 50Ω matching networks for both RF input
and output
• CDMA 95A/B, CDMA2000-1X/EVDO
ACPM-7821 is self contained, incorporating 50 ohm Applications
input and output matching networks.
• Digital Cellular (J-CDMA)
