Description
The ACPM-7831 is a fully
matched CDMA Power Amplifier
module. Designed around Agilent
Technologies new Enhancement
Mode pHEMT (E-pHEMT)
process, the ACPM-7831 offers
premium performance
in a small,
easy to use package.
Fully
matched to 50 Ohms on the
input and output allows faster
design, less overall system
optimization and more reliable
performance in production.
Designed in a surface mount RF
package, the ACPM-7831 is cost
and size competitive.
The ACPM-7831 is another key
component of the Agilent
CDMAdvantage
RF chipset.
The amplifier has excellent
ACPR and efficiency perfor-
mance,
at both high and medium
Applications
鈥?1900 MHz CDMA handsets
鈥?Wireless data terminals
