RF3145
0 QUAD-BAND GSM/EDGE/GSM850/DCS/PCS
POWER AMPLIFIER MODULE
RoHS Compliant & Pb-Free Product
Typical Applications
• 3V Dual/Triple/Quad-Band Mode Handsets • Commercial and Consumer Systems
• Portable Battery-Powered Equipment
• GSM850 and GSM900 Products
• EDGE and GPRS Class 12 Compatible
• DCS/PCS Products
Product Description
The RF3145 is a high power, high efficiency power ampli-
fier module with integrated power control. This module is
self-contained with 50Ω input and output terminals. The
device is manufactured on an advance Gallium Arsenide
Heterojunction Bipolar Transistor (HBT) process, and has
been designed for use as the final dual-mode
GMSK/8PSK RF amplifier in GSM, DCS and PCS hand-
held cellular equipment and other applications in the
824MHz to 849MHz, 880MHz to 915MHz, and in the
1710MHz to 1910MHz bands. Internal band select pro-
vides control to select the GSM850/GSM900 or
DCS/PCS band. The device is packaged on ultra-small
LCC, minimizing the required board space.
