RF5188
0 3V 1950MHZ W-CDMA LINEAR POWER
AMPLIFIER MODULE
RoHS Compliant & Pb-Free Product
Typical Applications
• 3V W-CDMA Band 1 Handsets
• 3V TD-SCDMA Handsets
• Multi-Mode W-CDMA 3G Handsets
• Spread-Spectrum Systems
Product Description
The RF5188 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 W-CDMA handheld digital
cellular equipment, spread-spectrum systems, and other
applications in the 1920MHz to 1980MHz band (Band 1).
The RF5188 has a digital control line for low power appli-
cations to lower quiescent current. The RF5188 is assem-
bled in at 16-pin, 3mmx3mm, QFN package.

Component
VCC BIAS can be connected to VCC; however, VCC must be maintained above 1.5 V.
L2 = 8.2 nH and may be needed to provide isolation between VCC1 and VCC2 depending on layout.
