RF5146
0 QUAD-BAND GSM850/GSM900/DCS/PCS
POWER AMP MODULE
RoHS Compliant & Pb-Free Product
Typical Applications
• 3V Quad-Band GSM Handsets
• GSM850/EGSM900/DCS/PCS Products
• Commercial and Consumer Systems
• GPRS Class 12 Compatible
• Portable Battery-Powered Equipment
• Power StarTM Module
Product Description
The RF5146 is a high-power, high-efficiency power ampli-
fier module with integrated power control that provides
over 50dB of control range. The device is a self-contained
7mmx7mmx0.9mm lead frame module (LFM) with 50Ω
input and output terminals. The device is designed for use
as the final RF amplifier in GSM850, EGSM900, DCS and
PCS handheld digital cellular equipment and other appli-
cations in the 824MHz to 849MHz, 880MHz to 915MHz,
1710MHz to 1785MHz and 1850MHz to 1910MHz
bands. With the integration of a VRAMP limiting circuit, the
RF5146 can regulate the VRAMP voltage to ensure mini-
mum switching transients. The VRAMP limiter function is
fully integrated into the CMOS controller and requires no
additional inputs from the user.
