RF3146A

RoHS Compliant & Pb-Free Product

Typical Applications

• 3V Dual-Band GSM Handsets

• Commercial and Consumer Systems

• Portable Battery-Powered Equipment

Product Description

The RF3146A is a high-power, high-efficiency power

amplifier module with integrated power control. The

device is a self-contained 7mmx7mmx0.9mm lead

frame module (LFM) with 50Ω input and output terminals.

The power control function is also incorporated, eliminat-

ing the need for directional couplers, detector diodes,

power control ASICs and other power control circuitry;

this allows the module to be driven directly from the DAC

output. The device is designed for use as the final RF

amplifier in GSM850, and PCS handheld digital cellular

equipment and other applications in the 824MHz to

849MHz, and 1850MHz to 1910MHz bands. On-board

power control provides over 50dB of control range with an

analog voltage input; and, power down with a logic “low”

for standby operation.
