RF5144
DUAL-BAND CDMA 800MHz/1900MHz
TRI-MODE POWER AMPLIFIER MODULE
• 3V CDMA/AMPS Cellular Handset
• 3V CDMA2000/1XRTT Cellular Handset
• 3V CDMA US-PCS Handset
• 3V CDMA2000/1XRTT US-PCS Handset
The RF5144 is a high-power, high-efficiency linear ampli-
fier module specifically designed for 3V handheld sys-
tems. The device is manufactured on an advanced third
generation GaAs HBT process, and was designed for use
as the final RF amplifier in 3V IS-95/CDMA20001X/
AMPS handheld digital cellular equipment, spread-spec-
trum systems, and other applications in the 824MHz to
849MHz band and 1850MHz to 1910MHz band. The
RF5144 has a digital control line for low power applica-
tions to lower quiescent current. The RF5144 is assem-
bled in a 24-pin, 4mmx4mm, QFN package.
