Agilent ACPM-7833
CDMA1900 (PCS)
Power Amplifier Module
Data Sheet
Features
• Operating frequency:
1850 – 1910 MHz
• 28.5 dBm linear output power
@ 3.4 V
• High efficiency: 40% PAE
• Dynamic bias control for low
midpower Idd
current with a single bias control
voltage. For even lower quiescent
current, a dynamic bias control
circuit can be used by varying
the voltage on the Vcntl pin
between 1.2V to 2.5V.
Designed in a surface mount RF
package, the ACPM-7833 is cost
and size competitive.
The ACPM-7833 is another key
component of the Agilent
CDMAdvantage
RF chipset.
• Very low quiescent current with
single control voltage
• Internal 50 ohm matching networks
for both RF IN/OUT
• 3.2 – 4.2 V linear operation
• cdma2000 1xRTT capable
• Only 3 SMT parts needed
• 4.0 x 4.0 x 1.1 mm SMT package
Description
The ACPM-7833 is a fully
matched CDMA Power amplifier
module. Designed around Agilent
Technologies’ new Enhancement
Mode pHEMT process, the
ACPM-7833 offers premium
performance in a very small form
factor. Fully matched to 50 Ohms
on the input and output.
The amplifier has excellent ACPR
and efficiency performance at
max Pout and low quiescent
Applications
• CDMA handsets
• Datacards
• PDAs
