POWER AMP MODULE

• GSM850/EGSM900/DCS/PCS Products

• GPRS Class 12 Compatible

• Power StarTM Module

Product Description

The RF3140 is a high-power, high-efficiency power ampli-

fier module with integrated power control. The device is

self-contained with 50Ω input and output terminals. The

power control function is also incorporated, eliminating

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 out-

put. The device is designed for use as the final RF ampli-

fier in GSM850, EGSM900, DCS and PCS handheld

digital cellular equipment and other applications in the

824MHz to 849MHz, 880MHz to 915MHz, 1710MHz to

1785MHz 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.
